When installing packages of operating updatessystems or when installing new software sometimes have to download files for the .NET Framework, but in some cases failures occur. Let's try to figure out what this component is and how to update the .NET Framework so that everything works like a clock.
What is the Microsoft .NET Framework?
The platform itself is present in any system.Windows It was originally developed by Microsoft to create programs and applications, use secure communications and much more.
However, over time, it turned intouniversal means to ensure the compatibility of programs written in different programming languages. Roughly speaking, if a certain application is not designed to function in the 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 issues of the update, by default.NET Framework can only be updated manually, because even when the system update is enabled, the packages for this platform are not installed, and the updates themselves mainly concern the security and safety system. How to do this will be shown below.
Service Pack Composition
Update platform Microsoft.NET Framework can update not only software modules, but also the main components of the development environment. Moreover, in the case of new features or support for additional structures, their installation will also be made.
In the list of updates, the following components can most often be observed:
- CLR (improved performance of multi-core processors, recognition of new file types and numeric data, easier debugging in mixed mode, including dumps and mini-dumps).
- Visual Basic and C + / ++ (work with implicit continuations of strings, new operators, dynamic dispatching).
- Modeling and simplified data access (WCF services and the Entity Framework composite platform).
- ASP.NET extensions (HTML and CSS ID management, dynamic data components, templates, filters, AJAX-based web forms).
- Composite WFP modules (multi-touch input, flexible scalability, SDK support, visual presentation).
- Windows Workflow (support of processes and projects, modeling styles).
- WCF (Correlation Based 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 the .NET Framework to 4.0: initial conditions
Now directly about the update. Microsoft.NET Framework can only be updated if the system fully complies with some initial conditions. It must necessarily contain a Windows installer of version not lower than 3.1, as well as Internet Explorer browser modifications 5.01 and higher.
In the event that such components in the systemNo, first of all it is necessary to update them, and only after that install updates for the whole platform. In addition, a prerequisite is the availability of installed latest updates and service packs for the operating systems themselves.
If for any reason they were not installed automatically, you should set up a manual search in the "Update Center" 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.
Поддерживаются операционные системы от XP до 10 и x86, x64 and ia64 architecture (some components are unavailable or not supported). In the minimum configuration, there should be a processor with a clock frequency of 1 GHz and higher, a RAM of 512 MB and more, and also about 850 MB of free disk space for 32-bit systems (or 2 GB for 64-bit architecture).
Update process
Sometimes in the process of installing some applicationsa message is issued that the .NET Framework needs to be updated (Windows 7 is used or any other supported system is not important). And here you should pay attention to one interesting fact. The fact is that installing a new version has nothing to do with the update process itself. A simple installation of a new version of the platform is performed. In this case, the installer first removes the old modification, and only then starts the installation of the new version.
Sometimes before installing a newer version of the latest version, you may need to remove the previous modification manually (this mainly applies to Windows XP).
.NET Framework can only be updated ifPre-downloading the installation distribution from the official Microsoft site (from other sources it is better not to take it, since it may be a modification that is incomplete in functionality and also infected with viruses and malicious codes). In extreme cases, before running the installer or unpacking the archive containing it, you need to check with an antivirus scanner.
After downloading the file, it remains necessary to run it as an administrator and wait for the installation process to complete.
Possible problems when updating and methods of their solution
However, despite the simplicity of the update process, problems may arise during installation. Most often this concerns version 4.0. The installer displays a message stating that the installation was not completed.
You can, of course, rebootcomputer system and try to re-install, but in most cases the effect is zero. Therefore, the .NET Framework can be updated with troubleshooting as follows.
Run the command line (cmd) from the menu"Run" (Win + R), prescribed in the console net stop WuAuServ. After this, 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 the command line, enter net WuAuServ start and repeat the installation. In 99.9% of cases, this technique completely eliminates the problem.
Instead of the total
As you can see, nothing complicated in updating the platform.NET Framework no. The main thing is to take into account the system requirements for computers for its correct functioning, install the latest updates for the "OS" itself and pay attention to the installed version if the package was downloaded not from an official resource, but from another source. In case of errors or failures, the described method gives almost 100% guarantee of correcting the situation.
