When installing a new software or operating system updates, in some cases you have to download files for the .NET Framework. Sometimes this operation fails. Let's try to understand what this component is and how to update the .NET Framework so that everything works correctly.

Microsoft .NET Framework: what is it?

The Microsoft.NET Framework itself is present in operating systems Windows family.Initially, this platform was developed by Microsoft specialists to create applications, programs, use secure communications and much more. Over time, this platform has turned into a universal tool that allows you to ensure compatibility of programs written in various languages programming. Speaking in simple words, If specific application or the program is not designed to function in Windows environment, then when using the Microsoft.NET Framework as an intermediary or bridge this program will be able to start up and work fully. As for the update issue, by default the .NET Framework can only be updated in manual mode. When system updating is enabled, packages for this platform will simply not be installed. The updates themselves, as a rule, concern mainly the protection and security systems. How to do this will be shown below.

Service packs: composition

Microsoft.NET Framework can update not only software modules, but also the main components of the development environment. If new features become available or additional structures are supported, they will also be installed. Most often in the list of updates you can notice improvements to the following components:

CLR - responsible for increasing the performance of multi-core processors, recognizing numeric data and new file types, lightweight debugging in mixed mode, including mini-dumps and dumps;
VisualBasic and C+/++ - allows you to work with implicit line continuations, new operators and dynamic dispatch;
Composite EntityFramework and WCF services - responsible for modeling and simplified data access;
ASP.NET extension - responsible for managing CSS and HTML identifiers, templates, dynamic data components, filters and web forms based on the AJAX library;
Composite WFP modules – provide multi-touch input, flexible scalability, SDK support and visual presentation;
Windows Workflow – project and process support, modeling styles;
WCF - correlation-based action programming, responsible for the performance of worker processors;
PLNQ queries and TPL library - parallel programming.

The full list of updates can be found on the official Microsoft website.

How to Upgrade .NETFramework to 4.0: Initial Conditions

Now let's discuss the update process itself. You can upgrade the Microsoft .NET Framework only if the system meets the fully defined initial conditions. IN mandatory it must contain the operating system installer Windows versions not lower than 3.1, and also Internet browser Explorer versions 5.01 and higher. If these components are not in the system, then first of all you will need to update them, and only after that install updates for the entire platform as a whole. Also prerequisite is the availability of service packs and the latest installed updates for the operating systems themselves. If for some reason they were not installed in automatic mode, you need to set up a manual search in the Update Center, and then integrate the found components into the system.

.NET Framework 4.5 Update: system requirements

When installing updates, you need to pay attention to the presence free space on the disk, as well as the system configuration. Supported operating systems Windows families ranging from XP to 10 with x86, x64 and ia64 architecture (some components are not supported by the system or are not available at all). The minimum configuration must use a processor with a clock frequency of 1 GHz or higher, RAM volume from 512 MB, 850 MB of free disk space for 32-bit systems and 2 GB for 64-bit systems.

Update process

In some cases, during the application installation process, a message appears indicating that the correct operation you need to update the .NET Framework. Here it is worth paying attention to one interesting point. The problem is that the installation new version has nothing to do with the update process as such. A new version of the platform is simply installed. The installer first removes the old modification and only then starts installing the new version. In some cases, before installing a newer version, you may need to manually remove the previous modification. This mainly concerns the operating room Windows systems XP.NET Framework can only be updated if you download it first installation distribution from the official website of Microsoft Corporation. It is better not to take it from other sources, as it may be an incomplete modification in terms of functionality, infected with malicious codes and viruses. Before unpacking the archive containing the installer and its direct launch you need to check the files using antivirus scanner. After downloading the file, you must run it as an administrator and wait for the installation process to complete.

Updating problems and methods to resolve them

Despite the apparent simplicity of the update process, certain problems may arise during installation. Most often this concerns version 4.0. The installer may display a message indicating that the installation was not completed. Of course, you can try rebooting the system and trying to perform the installation again, but in most cases the effect of such a procedure will be zero. Therefore, to fix problems, you can update the .NET Framework as follows: run the command line from the Run menu and enter the netstop Wu AuServ command in it. After this, you need to find the folder Software Distribution in the root directory of the system and rename it, for example, to SDold. After that, to command line you must enter net WuAuServstart and repeat the installation. This technique allows you to completely eliminate the problem in 99.9% of cases.

Instead of a conclusion

As you can see for yourself, there is nothing difficult about updating the .NET Framework. The main thing here is to take into account the system requirements that apply to computers for its correct functioning, to install latest updates for the operating system itself and pay attention to the installed version if the package was not downloaded from official resource, but from other sources. If errors or failures occur, the described technique provides a 100% guarantee that the situation will be corrected.

.NET Framework — software platform, published by Microsoft. The platform is based on the Common Language Runtime (CLR), which can run both regular programs, and server web applications. The .NET Framework supports the creation of programs written in different programming languages. The platform is necessary for the installation and correct operation of many programs, and therefore is necessary for users.

System Requirements:

Russian language only in the installer

Version 1.0 Currently, it is practically no longer used, so it is recommended to install it only when necessary, when working with programs that require it ( Visual Studio 2002, Sound Forge some versions, etc.). Version 1.1 does not include version 1.0, does not require or replace it during installation. It is used more often, but it is also recommended to install it when necessary, only for those programs that are strictly tied to it. This is due to the fact that the .NET Framework 2.0 provides backward compatibility with previous versions, and most programs written under 1.0 and 1.1 run without problems in the 2.0 environment (just as programs written under 1.0 can run under version 1.1). To avoid conflicts, it is not recommended to install versions 1.0 and 1.1 at the same time (they have some common registry entries). Versions 1.1 and 1.1 SP1 are included in the Windows Server 2003 and Windows Server 2003 SP1 / R2SP1 / SP2 / R2SP2 operating systems, respectively.
