What is Microsoft .NET Framework. How do I install and reinstall the NET Framework? Update framework to the latest version

When installing update packages for operating systems or when installing a new software sometimes you have to upload files for the platform as well. NET Framework but it crashes in some cases. Let's try to figure out what this component is and how to update the .NET Framework so that everything works like clockwork.

What is Microsoft .NET Framework?

The platform itself is present in any Windows system... It was originally developed by Microsoft to create programs and applications, use secure communications, and more.

However, over time, it has become a universal tool that allows you to ensure the compatibility of programs written in different programming languages. Roughly speaking, if a certain application is not designed to function in Windows environment, when using the platform as a kind of intermediary or bridge, the program will be able to start and work in full-featured mode.

As for the update issues, by default, the .NET Framework can only be updated manually, because even with the system update enabled, the packages for this platform are not installed, and the updates themselves relate mainly to the protection and security system. How to do this will be shown below.

Contents of service packs

An update of the Microsoft .NET Framework can update not only program modules, but also the main components of the development environment. At the same time, in the event that new capabilities appear or additional structures are supported, their installation will also be performed.

In the list of updates, you can most often see improvements in the following components:

• CLR (improved performance of multi-core processors, recognition of new file and numeric data types, lightweight debugging in mixed mode, including dumps and minidumps).
• Visual Basic and C + / ++ (working with implicit line continuation, new operators, dynamic dispatch).
• Modeling and Lightweight Data Access (WCF Services and Composite Entity Framework).
• ASP.NET Extensions (HTML and CSS ID Management, Dynamic Data Components, Templates, Filters, AJAX-Based Web Forms).
• Composite WFP modules (multi-touch, flexible scalability, SDK support, visual presentation).
• Windows Workflow (support of processes and projects, modeling styles).
• WCF (Correlation Action Programming, Workflow Performance).
• Parallel programming (TPL library, PLINQ queries), etc.

A complete list can be found on the official website of the corporation.

How to upgrade .NET Framework to 4.0: initial conditions

Now about the update itself. The Microsoft .NET Framework can only be updated if the system fully meets some of the initial conditions. It must contain Windows Installer version 3.1 or higher, as well as Internet browser Explorer modifications 5.01 and higher.

In the event that there are no such components in the system, first of all it will be necessary to update them, and only then install updates for the entire platform as a whole. Besides, a prerequisite is the existence of established latest updates and service packs for the operating systems themselves.

If for some reason they were not installed in automatic mode, in the "Update Center" you should set manual search, and integrate the found components into the system.

How to update .NET Framework 4.5 system requirements

When installing updates, you should also pay attention to the system configuration and the availability of free disk space.

Supported OS XP to 10 and x86, x64 and ia64 architectures (some components are not available or not supported). The minimum configuration must have a processor with a clock speed of 1 GHz or higher, RAM 512 MB or more, as well as about 850 MB of free disk space for 32-bit systems (or 2 GB for 64-bit architecture).

Update process

Sometimes, during the installation of some applications, a message appears that for them to work correctly, the .NET Framework must be updated (Windows 7 is used or any other supported system, it does not matter). And here it is worth paying attention to one interesting fact... The point is that the installation new version it has nothing to do with the renewal process as such. A new version of the platform is simply installed. In this case, the installer first removes the old modification, and only then starts the installation of the new version.

Sometimes, before installing a fresh version, you may need to manually remove the previous modification (this mainly applies to Windows XP).

NET Framework can be updated only in case of preliminary downloading of the installation distribution kit from the official Microsoft website (it is better not to take it from other sources, since it may be a modification that is incomplete in functionality, moreover, infected with viruses and malicious codes). As a last resort, before starting the installer or unpacking the archive containing it, the files must be checked with an antivirus scanner.

After downloading the file, it remains to run it as an administrator and wait for the installation process to finish.

Possible problems during the update and methods of solving them

However, despite the simplicity of the update process, problems can arise during installation. Most often this applies to version 4.0. The installer displays a message that the installation has not been completed.

You can, of course, reboot computer system and try to re-install the installation, but in most cases the effect is zero. Therefore, you can update the .NET Framework to fix the problems as follows.

Run the command line (cmd) from the Run menu (Win + R), write net stop WuAuServ in the console. After that, we find the Software Distribution folder in the root directory of the system (C: \ Windows) and rename it, for example, to SDold.

After that in command line enter net WuAuServ start and repeat the installation. In 99.9% of cases, this technique completely eliminates the problem.

Instead of a total

As you can see, there is nothing difficult about updating the .NET Framework. The main thing is to take into account system requirements presented to computers for its correct functioning, install the latest updates for the "operating system" itself and pay attention to the installed version, if the package was downloaded not from an official resource, but from another source. In the event of errors or failures, the described technique gives an almost 100% guarantee of correcting the situation.

I am often asked what the Microsoft .NET Framework is, what this software platform is for, how to check the installed version in the operating system, where to download and update it from, if necessary.

In this article I will try to answer all these questions in a simple and understandable language(with pictures).

What is Microsoft .NET Framework

I will not quote you Wikipedia and verbiage here with abstruse definitions - I will explain the purpose of this mysterious bunch program code literally "on the fingers".

Microsoft .NET Framework is one of the main components for the operating system Windows, which must be installed for all users.

I will not quote you Wikipedia and verbiage here with abstruse definitions - I will explain the purpose of this mysterious bunch of program code literally on my fingers.

Just imagine a "spare parts warehouse" in your computer for a huge number of different programs that can take the "spare part" they need from this "warehouse" at any time and thus unload your installer (installer), make it more compact and faster.

Let's say two programs use the same component (part of the program code) for their work - why install it twice with each program? And if there are dozens of such utilities in your computer? System disk"Will end" in this case, very quickly.

This development environment (Microsoft .NET Framework) can be compared to package of universal codecs for video playback or audio files. It is also very similar in principle to a common library of dll files for computer games(DirectX).

The scale of distribution of our "spare parts warehouse" for programs is very, very huge - almost every second computer program needs this component installed in the operating system. Moreover, it is used by all browsers and many sites on the Internet for their correct display and operation.

Are you impressed with the importance of having Microsoft .NET Framework on your computer? Move on…

How to check the Microsoft .NET Framework version

You can check the installed version of Microsoft .NET Framework on your computer (or even its presence) through system registry , without third-party programs.

I won't tell you about this method, because inexperienced users can do a lot of trouble in their registry if they get distracted for a second and accidentally delete a line or a whole branch (oh, it’s itself 🙂).

Moreover, my method of checking the version of the Microsoft .NET Framework package described below is more convenient, clear and practical.

We will check the presence and relevance of one of the most important components of the Windows operating system on our computer using the absolutely free, small and portable ASoft .NET Version Detector program.

ASoft .NET Version Detector Program

After starting this utility, you will see, at first glance, an incomprehensible multi-colored window ...

... but it's actually very simple. The versions of the software environment already installed are shown in white, and not installed in gray.

In most cases, the latest (newest) package contains the most important parts. previous versions, but there are "especially harmful" programs, which should be given exactly full version 1.0 or 1.1.

You can update Microsoft .NET Framework or download a specific version by clicking on the green down arrow icon ...

You will be taken to the official download page for the offline installer ...

Such an installer can be copied to a USB flash drive and installed on any computer, even without an Internet connection.

As you can see in the screenshots above, I have the most current version Microsoft .NET Framework. Modern Windows 10 monitors this very carefully. If you have disabled automatic update systems or your "operating system" is not as smart as "ten" - ASoft .NET Version Detector will save the day.

Download ASoft .NET Version Detector

Here's a link to the official website of the program ...

The size of the compressed folder with the portable program is only 408 kb.

The search engine gave me an unofficial site in the first place in its results, and this is what came of it ...

Such a terrible and wrong verdict was given to me by an outdated version of the program downloaded from some "left" site. So much for you official sites of computer programs.

Good day.

It is not so uncommon to encounter various errors associated with Microsoft package.NET Framework (most often in games, various editors, drawing programs, take at least the same AutoCAD ...).

In all such problems, you need to find out which version of the .NET Framework the application needs, see if it is in Windows, and if it is not there, update / install. It would seem nothing complicated, but there are nuances. They will be discussed in the article ...

For reference. In general, the .NET Framework is a special package that is designed to combine various software written in different programming languages ​​with each other (so that everything works). In theory, you can compare it with codecs. Naturally, if you do not have on your computer the version you want(or it was damaged) - then the program will not start for you.

And now, closer to the point, I will analyze the most basic ...

How do I know which versions of the .NET Framework I have installed?

Method number 1

You need to open the panel Windows management along the following path: (approx. : Installation and removal of programms).

Important!

Note that in Windows 8 and 10, Microsoft .NET is not listed installed programs(to see the versions, you need to open the link in the menu on the left "View installed updates").

There is no option to uninstall .NET in Windows 10 regular means, however, it is usually possible to install latest version.NET (update it).

Method number 2

For viewing and solving problems with .NET there is special utility".NET Version Detector" (available at the link:).

It doesn't require installation. After launch, it will show a list of all installed versions and will also lead download links (if suddenly something does not appear, you can download and install).

Is it possible not to update this package, because I have not updated it before and everything worked?

Most users do not even remember about it (for the time being ...). The fact is that in new versions of Windows there is already a specific version of .NET included (preinstalled in the system) and there is no need to separately download or update something.

In addition, .NET is often included in the installers of popular games, and when they are installed, this package is also updated. Those. all actions are invisible to the user ...

However, it may be that new program or the game will require new package.NET (or vice versa, want to run something old that will require a specific version of .NET and no other).

And then everything is simple: if the required version of .NET is not available, then at startup you will see an error (as in the example below). By the way, some of the errors may be related to the "broken" version of .NET (that is why, sometimes it is recommended to update this software).

Firstly, I want to advise right away: you do not need to download all versions in a row and try to reinstall each (a little below I will note which versions are recommended for different OS). Secondly, it is recommended to download .NET only from the official Microsoft website (so to speak, not a modified installer).

Method number 1. A little higher in the article, I recommended you to use the ".NET Version Detector" utility - it will not only show you what versions of the .NET package you have installed on your system, but also provide download links for each version.

• (for Windows XP);
• (includes .NET 2.0, 3.0; for Windows XP, Vista);
• (for Windows XP, Vista and 7);
• (for Windows 7, 8 and 8.1);
• (for Windows 7, 8, 8.1 and 10);
• (for Windows 7, 8, 8.1 and 10).

It is important to note that .NET 4 version (say) upgrades the previous .NET version, so newer Windows 8, 10 OS requires installing (in 99.9% of cases) only the latest .NET 4 versions.

Addition!

I can't help but recommend the program - even if you don't need to update your drivers, try using it anyway. The fact is that it automatically detects missing components in the system that may affect games (.NET, Visual C ++ and other packages), and installs them. Agree, it's convenient!

Please note that the program downloads and installs everything necessary for games (.NET, Visual C ++ and other packages) automatically!

Can I uninstall the .NET Framework (or use a different version)? What does that require?

In most cases, you do not need to remove the package - you just need to use a different version. This can be done in the tab (which can be opened in the Windows Control Panel - just above the article shows you where to find this) .

Actually, you need to put a "tick" next to the package that you want to use and agree to the changes (Windows OS may need to download the missing files - it does it itself in auto mode (just need an internet connection)).

In those cases when you seem to have the required version of .NET installed, but the game (program) still throws errors and "swears" - you can try to uninstall the .NET package and reinstall it.

In some cases, the package can be removed by opening the list of installed programs ( Control Panel \ Programs \ Programs and Features ). Removal occurs in the same way as any other program (see screen below).

In some cases, a special utility may be required: NET Framework Cleanup Tool (link to Microsoft developer blog -).

The utility does not need to be installed. By the way, you need to run it as administrator (approx. : i.e. right-click on the executable file and in context menu select "run as administrator") .

That, in fact, is all for today.

Add-ons are welcome ...

All the best.
