Assigning Microsoft .NET Framework

Microsoft .NET.Microsoft .NET Framework is an integrated in OS Windows, a consistent and comprehensively developed programming model. It is used to create high quality provided by an excellent interface, and is distinguished by security and transparency of network connections.

The core of the platform is a multilingual programming environment called Common Language Runtime (CLR). It is believed that the Framework was developed as a response to a popular Java platform from Sun.

Why install it?

When one of the applications or the installation of installation requests the installation of Microsoft .NET Framework, not many agree, without understanding why it is necessary. Some of the users do not install the package that comes in the kit, because they have already installed one of the frameworks.

However, those and other wrongs. Be sure to install exactly the version (V4.0, 2.0, 3.5, 4.5) Microsoft .NET Framework, which requires this or that application. Since it will only work stably on the platform on which it was developed, even if you have installed the software package of the latest version.

Such interrelation of applications with the platform is simply explained. This is done so that the developer is not tied to the operating system and the discharge of the user processor. For example, if a software version created on the version V4.0, 2.0, 3.5, 4.5, 4.5 is running on the PC, it is necessary that support (or implementation) is installed in the form of Microsoft .NET Framework v4.0, 2.0, 3.5, 4.5 .

Important components

You need to know what Microsoft .NET Framework is made of two parts:

  • Executive environment;
  • Connected library.

The main component can be called COMMON LANGUAGE RUNTIME (CLR). It can execute the program part of the usual applications or server, being an executing medium.

The second half is needed not less. Framework Class Library (FCL) is a library of classes in which there are quite a lot of items to handle:

  • databases;
  • networks;
  • interfaces;
  • files;
  • input and data output.

All this makes it possible to develop ready-made classes to create programs, bypassing a low level part.

Platform Support Installation

Microsoft .NET Framework installer has been added to Windows OS by default. Version V4.0, 2.0, 3.5, 4.5 platform depends on the operating system. But virtually any of them can be needed independently if your computer meets the requirements.

Requirements of the .NET platform

As in the case of any applications, the .NET platform also has its own requirements for normal support for programs. The newer version of (V4.0, 2.0, 3.5, 4.5), the large characteristics of the PC requires it.

However, applications developed on this platform are more sensitive to performance. That is, if you use an old computer, you will not install programs under Windows 8, and therefore the version 4.5 platform you do not need.

To install Microsoft .NET Framework any version (V4.0, 2.0, 3.5, 4.5) you will need:

  • operating system of the WINDOVS family, starting with XP SP3 or Server 2003 SP2;
  • computer with a processor from 1 GHz;
  • not less than 512 MB of RAM;
  • Any version of the processor architecture, starting with x86.

Installation process by

It is necessary to take into account such a fact: there will be two programs for installation, as a rule, built into the operating system. If you are using XP without updates, you need to download them from the official site of Microsoft. Minimal versions that you need:

  • Windows 3.1 installer;
  • Browser fifth version of Internet Explorer.

Find out which version you have installed, you can view all the components. But before starting the installation, it is desirable to update all the system software. In order to do this, follow these conditions:

  1. Open control panel;
  2. Find the "Windows Update Center";
  3. Check availability of important updates and install them.

Windows Update Center

Download any version (V4.0, 2.0, 3.5, 4.5) Microsoft .NET Framework on the official website of Microsoft.

Microsoft Download Center

Some of the applications themselves offer the installation of that version (V4.0, 2.0, 3.5, 4.5), which they need. Adding one component may include several more, depending on the needs of software, as well as the platform itself (for example, together with the 3.5 platform, 3.0 and 2.0 are installed).

Windows components

The installation itself is very simple and intuitively understandable. If the component fails during installation, or the system issues an error message, you need to disable or delete all versions (V4.0, 2.0, 3.5, 4.5)

Delete and disable framework

Installing Microsoft .NET Framework

Why delete frameworks? If you have a problem after updating one of the Windows components, you can perform the following steps:

  1. Try turn off the last installed element;
  2. Remove it with standard means;
  3. Use a special Net Framework Cleanup Tool utility.

Restoring work with standard Windows tools

To disable the component, you need to go to the "Control Panel", "Enable and disable components". Find a version (V4.0, 2.0, 3.5, 4.5), which was installed last and removed a tick (deactivate), then click the "OK" button.

Windows components

If the problem occurred not when installed, but when Windows startup, it was most likely a failure in the system. If the error is critical and does not allow you to boot, then you need to solve the problem in safe mode. In order to get rid of failures, remove the framework programs through the standard "Installation and Removing Programs".

The installing and deleting of programms

When you delete, start with the most installed version and complete the minimum. That is, in order of turn Uninstall V4.0 - 3.5 - 3.0 - 2.0 - 1.1 after that you need to download the versions you need from the official website.

Using additional software

Due to the numerous versions, the failures are quite diverse. Windows staff does not always help completely remove software, leaving unnecessary registry entries, settings files and system libraries.

It subsequently can cause even more serious problems. Therefore, a special program for deletion was created - Net Framework Cleanup Tool.

.NET Framework Setup Cleanup Utility

The utility is very simple. After running it, you need to click the "CleanUp Now" button. NET Framework CleanUp Tool works so that it removes all the traces of the component action, including:

  • software;
  • Related updates;
  • registry entry;
  • settings files;
  • System libraries.

Thanks to this program, you can remove unnecessary old components without any problems and consequences, as well as get rid of the operating system errors in case of incorrect installation or component failure.

Microsoft Net Framework What is this program and is it necessary

What is Microsoft Net Framework?

What is the Microsoft Net Framework program?

Many users who open the list of installed programs on their computer are detected by Microsoft Net Framework there. It can be several versions (1.0, 2.0, 3.0, 3.5, and so on) and almost always installed up to version 4.5.

In this article we will tell you what is Microsoft Net Framework and whether to delete it, because almost always this question arises in connection with the lack of free space on the system disk.

What is Microsoft Net Framework?

The fact is that this is not a completely program. Microsoft Net Framework is a software environment (platform) inside which or using which various games and programs are being developed.

To work these most programs or games, the Microsoft Net Framework is required on the computer, as it is like a link, thanks to which your operating system understands how to execute the code that you specify it while running a program or game.

Nowadays, almost all games and programs are written using Microsoft Net Framework. That is why when they are installed, it is necessarily necessary to establish this software environment.

Is it possible to remove Microsoft Net Framework?

Definitely no! If you do this, most of the programs and games on your computer are simply refused to work, issuing an error with missing files when you start.

What is needed by Microsoft .NET Framework, and where to download it.

From time to time, when downloading and installing programs, the computer shows errors associated with the lack of a certain Microsoft .NET Framework. Two most frequent error messages? Either .NET Framework is not installed on the computer, or its outdated version is installed. Link to download Net Framework 4.8 is below the article. There are detailed instructions for choosing and installing.

So what kind of beast is? This is a program without which modern Windows OS is not themselves. The most important component of Windows.

What is .NET Framework?

First of all, it is pronounced this miracle yudo, as "dot no framework." "Point-no" in Russian (well, almost in Russian). Dot Net.

To answer the question what the .NET Framework for Windows, you need to understand why he exists at all. Links to download the program are located below (these are official Microsoft servers) - while it hits, take a look at the explanation. It's quite simple, although you have to dive into some programming issues. No, the programmer for understanding "Dot-Neta" should not be.

So: Programmers are those people who create programs. Their work implies that they write code. They write code they are in different programming languages. Code - explanations for a computer, what to do at every moment of his work.

Any programming language is a pretty primitive thing. In programming languages ​​there are expressions of the type of addition or multiplication, but nothing more complex. Programmer wants to display the program window? He will need to write a bunch of code for this and spend a lot of time.

This looks like the code on which programs are written. If you do not download NET Framework for Windows, the computer will not understand anything either.

This looks like the code on which programs are written. If you do not download NET Framework for Windows, the computer will not understand anything either.

And here to help the programmer comes .NET Framework for Windows: You can download it for free. The essence of this software is a huge collection of code libraries already written for programmers that allow you to display the same window. Such code was written by Microsoft specialists. It allows programmers not to be distracted by unnecessary things, but to create their own programs.

Visual example. In the depths of the .NET Framework there are many detailed operations of operations - say:

  • Instructions for Windows, how to draw a window on the screen;
  • Ready function to put the buttons inside the window;
  • what exactly to make a computer when pressing these buttons is happening;

The programmer sufficiently enable such operations in your own code, and not spend a few days to explain the computer of elementary things. But the power of .NET Framework extends far beyond the boundaries of simple collections of code and ready-made functions. This development environment provides programmers to the smart features to speed up the creation of programs, so that these programs are deeply implemented in Windows services.

Well, Net Framework is a chopstick for programmers. Why is it an ordinary user?

The fact is that while there is no .NET Framework on the computer, Windows does not know how to work with programs written in this environment. So pop up the error screen: "This program requires Net.Framework installation". Such programs are more and more - these are drivers video cards Radeon and GeForce, graphic editors of type Paint.Net, numerous messengers, etc.

So, for the normal operation of many programs, Windows requires the .NET Framework (more precisely - it is part of the Redistributable Package - "distributed package"). It is not necessary for programmers - it is needed for ordinary users so that downloaded programs are launched on their machines.

Where to download .NET Framework. What versions are suitable for windows 7, 8 and 10

Most computers with Windows on board are already installed .NET Framework - usually old versions. Namely:

  • The installed .NET Framework version 3.5 has already been built in Windows 7.
  • Windows 8 and 8.1 are supplied with versions 4.5-4.5.1;
  • Windows 10 includes version 4.6.

Modern applications require fresh. Yes, and for overall security, it is better to download .NET Framework of the Fresh Version (at the end of 2019 it is 4.8). Suitable for Windows up to the old one already "seven". Installation is extremely simple.

In fact, the latest versions of the program are downloaded automatically through the update service (Windows Update). But too often it is disabled (how to disable updates in Windows 10 - a whole article on WooComp was devoted to this craft), so you can use the usual download from the Microsoft website. Everything is free, of course.

The most recent version of .NET Framework 4.8 (2020) is suitable for downloading and installing on Windows 10, Windows 8.1 and Windows 7 SP1. Choosing a bit (x86 or x64) is not required. The full version of the distribution takes about 60 megabytes.

The Microsoft website has two installer versions:

  1. Online installer. The tiny utility is under 2 MB, which runs the remaining files in the background. We do not recommend that at all.
  2. Offline installer - no more than 60 MB. Check it yourself - and save for the future. Perhaps it is useful when reinstalling Windows or for other computers.


The installation itself is extremely simple, takes 2-3 minutes depending on the power of the computer.

  1. Download .NET Framework 4.8 Runtime from Microsoft (full version, 111.9 MB). Select the Russian language from the list if it is.
  2. Run the downloaded file.
  3. Ready!
Download .NET Framework from the official site Microsoft

Download .NET Framework from the official site Microsoft

Version 4.8 independently deletes from the computer previous .NET Framework releases, starting with version 4.0 (more specifically - version 4, 4.5.2, 4.5.1, 4.5.2, 4.6.2, 4.7, and so on, will be deleted during installation). They do not need to uninstall manually. Older versions (3.5 SP1 for example) are separate programs. They will not be deleted independently, and in general it is better to leave them for compatibility with old programs.

How to find out which versions of the .NET Framework installed in the system?

This can be done through the system registry.

Run the registry editor: Start -> Run -> Regedit .

Go to section HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Net Framework Setup \ Ndp

We see branches with version numbers and additional parameters.

Install = 1. - He says that the version is installed. Sp. - Shows the number of the installed Service Pack. Version. - Shows the full version number.

What's new in Net Framework 4.8

The list of changes in version 4.8, which came out in the summer of 2019, includes:

  • improved screens support with high permissions;
  • Advanced support for the touch screenshots in Windows 10;
  • improved cryptography support;
  • Support for languages ​​C # 7 and VB 15;
  • Improvements in productivity and reliability framework.

Do not postpone the installation of this important Windows component. Download Net Framework 4.8 You need as soon as possible: many mistakes will go out of the system.

What is Microsoft .NET Framework and why it is installed on my PC?

ЕIf you use Windows for a very long time, then you probably heard about Microsoft .NET, because any application asked you to install it, or you noticed it in the list of installed programs. If you are not a developer, then you do not need a lot of knowledge to use it. You just need him to work. But, as you are on this village, you are interested in the details about what .NET is and why it needs many applications.

.NET Framework.

The name ".NET Framework" in itself is a bit incorrect. Framework (in terms of programming) is actually a set of application programming interfaces (API) and the general code library that developers can call when developing applications, so that they do not need to write code from scratch. In .NET Framework This general code library is called the Framework (FCL) library. Code bits in the general library can perform all sorts of functions. For example, the developer is necessary that its application can perform ping another IP address on the network. Instead of writing this code yourself, and then record all the bits and fragments that must be interpreted what the Ping results mean, they can use the code from the library that performs this function.

And this is just one tiny example. .NET Framework contains tens of thousands of common codes. This general code facilitates the life to developers, because they do not need to write a new function every time their application must perform some general function. Instead, they can focus on the code that is unique to their applications and the user interface that binds it all together. Using the structure of a common code similar to this also helps to provide some standards between applications. Application users can count on things like "Open" and "Open" dialog boxes that work equally in different applications.

So why is this name incorrectly?

In addition to use as a common code, the .NET also provides an application for applications. The execution environment provides a virtual sandbox machine in which applications are launched. Many development platforms provide identical things. Java and Ruby On Rails, for example, provide their own runtime environments. In .Net runtime is called Common Language Runtime (CLR). When the user starts the application, the code for this application is actually compiled into the machine code during execution and then executed. CLR also provides some other services, such as control of memory and processor flow, program exception processing and security management. The runtime environment is a way to abstract application from real equipment on which the application works.

What is Microsoft .NET Framework and why it is installed on my PC?There are several advantages of using applications in the execution environment. The most tangible of the advantages is tolerability. Developers can write their code with any of those supporting languages, including such as C #, C ++, F #, Visual Basic and several dozen others. Then this code can be started on any hardware that supports .NET. This platform was allegedly designed to support equipment other than Windows-based PCs, but its corporate character led to the fact that it was mainly used for Windows applications.

To solve this problem, Microsoft has created other .NET implementations. Mono is a free open source project designed to ensure the compatibility of .NET applications and other platforms, especially with Linux. The implementation of the .NET CORE is also a free open source platform designed to create lungs, modular applications on multiple platforms. .NET CORE is designed to support Mac OS X, LINUX and Windows (including support for universal Windows Platform applications).

As you can imagine, such a platform, like .NET, can become a real find. This allows developers to write code using your favorite programming language and be sure that the code will be able to work everywhere where Framework is supported. Users receive advantages from compatible applications, as well as from the fact that many applications may not be developed at all if the developers do not have access to Framework.

How does the .net appear on my PC?

.NET Framework has a somewhat winding history and have seen several versions over the years. As a rule, the newest version of the .NET is included in the release of each version of Windows. The versions were intended for reverse compatibility (so the application written for version 2 can work if version 3 has been installed), but it does not work so well. Not all applications worked with newer versions. In systems running Windows XP and Vista, you often see several different versions of the .NET installed on the PC.

There are three methods with which a specific version of the current framework was installed:

  • Perhaps your version of Windows included this default version.
  • An application requiring a specific version can set it during its installation.
  • Some applications will even redirect you to the site to download Set a specific .NET Framework version.

Fortunately, in modern versions of Windows, more and more smooth. Once on Windows Vista, two important things happened. At first, the .NET Framework 3.5 was released. This version was reworked to enable components from versions 2 and 3. Applications that require earlier versions will now work if you install version 3.5. Secondly, the updates for .NET Framework finally began to be supplied through the Windows Update Center.

Together, these two things meant that developers can now largely rely on users who already installed components, and no longer need to ask users to perform additional installations.

When Windows 8 was released, then a new, fully revised version of the .NET Framework version 4. Version 4 (and above) does not support backward compatibility with old versions. It is designed in such a way that it can be launched next to version 3.5 on one PC. Applications written in version 3.5 and below will require installations of version 3.5, and applications written on version 4 or higher will need version 4. Good news is that you, as a user, no longer need to worry about these installations. Windows largely copes with all this.

Windows 8 and Windows 10 include version 3.5 and 4 (current version now - 4.7.1). They are installed primarily, so when the application is first connected, which needs one of these versions, Windows will automatically add it. You can add them to Windows yourself if you want by contacting additional Windows features. You have options for adding version 3.5 and version 4.x separately.

What is Microsoft .NET Framework and why it is installed on my PC?However, there is no real reason for adding them to your installed Windows yourself if you are not developing applications. For the first time, when you install an application that needs one of the available versions, Windows will add it automatically for you.

What can I do if I have problems with .NET?

Probably, you will not come across problems with the .NET itself in modern versions of Windows. Since both required versions are included in Windows and are installed as needed. In older versions of Windows (XP and Vista) you often had to delete and reinstall various versions of .NET to make everything work. You also needed to make sure that the correct .NET versions are installed for applications that need them. Now Windows does it herself.

However, if you have any problems that, in your opinion, are related to the .NET platform, you can take a few steps.

First, you must make sure that Windows has all the latest updates. If the update for .NET Framework is available, it can solve your problems. You can also try to delete .NET Framework versions from your computer, and then add them again. If none of these steps work, you can try to scan system files in Windows for the presence of damaged. It does not take much time, and can restore system files that have become corrupt or disappeared. Always try.

If it does not help, then try downloading and run Microsoft .NET Framework Repair Tool. The tool supports all current .NET Framework versions. It helps to eliminate common problems when setting up or updating .NET and can automatically eliminate any problems that you encounter.

What is Microsoft .NET Framework and why it is installed on my PC?And here you have it. It may be more than you have ever wanted to learn about .NET Framework, but we believe that this is not unnecessary information.

Using popular software, most users do not think that complex processes occur in the operating system. Why and how the program works, that it uses for resources, because of which errors and the like appear. In fact, only some applications are able to run autonomously, regardless of the availability of those or other software components in the system. The lion's share requires a suitable configuration. A good example is the lack of NET Framework when installing and starting certain applications.

Error due to lack of the desired version of Net Framework

NET Framework - What is it necessary and can I remove

We have already found out that many programs will not work normally without some additional modules, such as Net Framework. Users Winfows 7/10, for sure, have repeatedly met with this component, but it was unlikely to think about his role and the functions performed. We hurry to fill this gap.

So, what is Microsoft .NET Framework, what is it needed and can it do without it? If we speak in a simple language, the NET Framework is a set of DLL libraries or a universal program code used by different programs. True, such a definition is hardly shedding enough light on the subject of the subject, so we will deepen a little in history.

The fact is that the original Windows system, as a platform, was focused on the programming language with, on which the application intended for it should be developed. However, this language was not too convenient and moreover a little suitable for creating complex structures. The appearance of OPP and C ++ significantly simplified the development of software, but as new operating systems and processor models appear, the programmers became increasingly faced with incompatibility problems.

We needed a certain overall platform that allowed working to work in a variety of applications in different versions and editions of Windows. At that time, the system already had a set of DLL libraries, but again they also supported only applications written in S.. There were more serious problems that had to solve Microsoft, for example, an unmanaged code that preventing the delimitation of rights for running programs.

The solution was the integration of the Java virtual machine developed by Sun and served as if a layer between Windows, third-party applications and a hardware of the computer. However, Microsoft and Sun cooperation turned out to be short-lived, and in 2001, Microsoft introduced its own universal platform for developing applications that received the name .NET Framework and who put the point in compatibility.

Net Framework.

Being a versatile, the NET Framework module allows you to run the NET software support not only on Windows, but also in other systems, and the program can be developed in any programming language, including those languages ​​that Windows does not understand. Of course, such software requires certain conditions, but the very fact that this is possible is a big plus of the NET Framework platform.

To the question of what is the Net Framework program and whether it needs, we need to believe, answered. Is it possible to remove it, say, for the sake of saving space on the hard disk? Yes, with the exception of the version that comes with Windows. Do this, however, is not recommended without special needs, as some third-party programs depending on Net Framework can stop running.

How to find out which version of Net Framework is installed

Now go to the next no less important issue. Software requirements are often indicated that the program needs such a version of the framework. In this regard, the user may need to know which Net Framework is installed in its Windows 7/10. It is not difficult to do it - there are several ways to find out which version of the component is in the system.

Using conductor and command line

All NET Framework packages are installed in directories. C: /Windows/ и / Framework64. (in 64-bit OS). Each version corresponds to a separate directory, the name of which begins on V (version), for example, v3.0, v3.5 and so on. Accordingly, it is not possible to determine the editorial board of the component, if you go through in the explorer at the specified address and see the names of the folders.

Folder with Net Framework packages

Alternatively, the contents of the directories can be displayed on the command prompt by running the command. Dir% Windir% / / Framework / V * / O: -N / B . According to the results of the request, all the installed version of the framework will be shown in the console, with the exception of version 4.5, located in the V4.0.XXX folder.

Display all versions of Microsoft Net Framework on the command prompt

Via registry editor

Another technique involves the use of the registry. Running the team regedit. Registry editor, expand the branch in the left column HKLM / Software / Microsoft / Net Framework Setup / NDP . In the last subsection, you will see the folders whose names will correspond to the NET Framework versions available in Windows.

View installed versions of Net Framework in the registry

To determine if the Net Framework 4.5 is installed in the system and above, go to the location. V4 / FULL And pay attention to Install and Version parameters. The value 1 for the first parameter will mean that the component is installed and active, the value of the second parameter contains the full number of the component version. The same applies to other editors of the framework. The lack of the FULL subdirectory will indicate that the NET Framework 4.5 or later component is not installed.

Learning through the registry, is it installed in the system NET Framework 4.5 or higher

With third-party utilities

Those who do not want to bounce themselves in the registry, we recommend using third-party tools. Download from the developer site utility "ASOFT .NET Version Detector" and run. The utility will display a list of installed framework versions at the bottom of the window in the field with a blue background. Also, Tulza will show the component updates.

How to download Net Framework for Windows 7/10

Many third-party programs that require NET Framework for their work, are able to initiate download and install the package, but a number of cases will have to be engaged in the user. You can find and download Net Framework without problems on the official Microsoft website, going to and selecting the desired version of the component.

The library set is also available on third-party resources, for example, on

How to download Net Framework from

As for the installation procedure, it is almost no different from installing most desktop programs. Regardless of which version of Windows you use, it is necessary that the Early Versions of Net Framework 3.5 and separately the last NET Framework version 4.7.1 are installed on your computer.

Installing Net Framework in Windows

Net Framework value

Even knowing what Net Framework is, ordinary users somehow do not think about the value and significance of this component. Otherwise, software developers belong to it. For them, and especially for those who program on Visual Basic .NET and C # net Framework, it is more than just a set of libraries. This is a full-fledged development environment that hides a lot of opportunities and tools, without which the creation of modern applications for the Windows operating system would be a difficult task.

I think that many of you have come across a program called Net Framework, since when installing third-party programs on a computer under Windows control, it often pops up a message that without this NET Framework itself is not possible.

What is needed by Net Framework. Replies Aytichnik

The essence of this issue is that all sorts of Windows programs can be written in different programming languages ​​and even one program may consist of different parts that are in turn written in different languages.

Therefore, in order for all sorts of programs to work successfully running Windows to Microsoft developers, a software platform called Net Framework has a lot of its versions at the moment.

If all of the above translate to a more understandable language, all programs have their own code and NET Framework converts it to a more understandable code for itself and the output is executed this code in the Windows operating system.

There are several ways to install NET Framework:

First method It is an independent download on the Microsoft website, with a subsequent installation on your computer (you need to pay attention to your version of the operating system and choose the current version of Net Framework).

Second way This is a banal update of the Windows operating system, which may contain NET Framework.

What is needed by Net Framework. Replies Aytichnik

Third way When installing programs for example, it may already include Net Framework or asks your permission and independently downloads and install Net Framework on your computer.

The NET Framework program works in automatic mode and does not require any gestures from the user, so you can safely install and forget about this program.

The only nuance may be that the old Windows operating systems may not support the new versions of Net Framework and on the contrary, new Windows does not support old version of the framework.

I will be very happy if you have learned something new from all over the above, and I will try to publish only useful and current articles in the field of IT technologies and not only.
