Download net framework v 4.0 app. What is Microsoft .NET Framework. How to install and reinstall NET Framework
The .NET platform, developed by Microsoft, is an integral part of most games and programs that run on Windows. In the user's understanding, .Net Framework 4.5 and 4.0 represent the basis for launching programs in the development of which this platform was used. It has become the standard for developing web applications, so if it is not available, there is a high probability that you will encounter them incorrectly. In addition, the lack of files for the correct version of the .NET Framework can cause the games to fail to run.
Starting with Windows 7, this platform comes bundled with the OS distribution, but a separate installation may be required if the required version is missing on the computer, or the .NET Framework has crashed.
Program versions
The most common and necessary ones today are .NET Framework 4.0 and .NET Framework 4.5. The first comes standard with Windows Vista and Windows 7, the second comes with Windows 8, however, regardless of which system you have, it is better to download and install both versions to avoid problems with running games and programs.
How do I know which versions of the .NET Framework are installed on my computer?
This can be done in two ways:
- Download and run ASoft .NET Version Detector from the developer's official website.
- Look in the system registry. For this:
- start the registry editor via Start - Run - regedit;
- open the section HKEY_LOCAL_MACHINE \\ SOFTWARE \\ Microsoft \\ NET Framework Setup \\ NDP;
- branch names correspond to installed versions.
.NET Framework 4.5
This version comes with the Microsoft Visual Studio 2012 package. To install it separately, you just need to download the .NET Framework 4.5 distribution kit for free from the official website and follow the instructions of the installer.
NET Framework 4.5 is usually not available by default on Windows 7 and must be downloaded manually. For this:
- Download .NET Framework 4.5 from Microsoft Official Site
- Follow the instructions of the web bootloader and installer.
The installation process is extremely simple, but it is important to remember that earlier versions of Windows (XP and below) do not support the .NET Framework 4.5.
.NET Framework 4.0
The previous version of the platform, which is automatically supplied with the distribution of Windows 7. Despite the update to version 4.5, it is still up to date. Most applications work seamlessly with the .NET Framework 4.5, however some may still require an older version.
You will also need version 4.0 if your OS does not support version 4.5.
The installation process is just as simple.

- The .NET Framework is Microsoft's comprehensive and consistent programming model for building applications that have a superior user interface, transparent and secure communications, and the ability to create diverse business processes.
The .NET Framework 4 works alongside its previous versions. Applications based on previous versions of the .NET Framework will continue to run on the platform for which they are designed by default.
Microsoft .NET Framework 4 contains the following new features and enhancements.
- CLR (Common Language Runtime) and BCL (Base Class Library) improvements
- Improved performance, including better support for multi-core computers, background garbage collection, and attaching a profiler on the server.
- New types of memory-mapped files and new numeric types.
- Easier debugging, including dump debugging, Watson minidumps, mixed mode debugging for 64-bit processors, and code contracts.
- For a complete list of extensions for the CLR and BCL, see.
- New features in Visual Basic and C #, such as lambda operators, implicit line continuation, dynamic dispatch, and named and optional parameters.
- Improvements in data access and modeling.
- The Entity Framework enables developers to program relational database operations using .NET objects and Language Integrated Query (LINQ). It includes many new features, including persistence ignore and POCO support, foreign key mappings, slow loading, test-driven development support, functions in the model, and new LINQ operators. Additional capabilities include support for multi-tier data processing applications with self-tracking entities, custom code generation using T4 templates, first model development, improved designer interface, improved performance, and pluralization of entity sets. For more information see.
- WCF Data Services is a component of the .NET Framework that allows you to create REST-based services and applications that use the Open Data Protocol (OData) to provide and retrieve data over the Internet. WCF Data Services contains many new features, including enhanced BLOB support, data binding, row counting, feed tuning, projection, and query pipeline enhancements. Native integration with Microsoft Office 2010 now enables Microsoft Office SharePoint Server data to be exposed as an OData feed and to be accessed through the WCF Data Services Client Library. For more information see.
- Extensions in ASP.NET
- Additional HTML controls, element IDs, and custom CSS styles to make it easy to create standards-compliant web forms that are optimized for search engines.
- New dynamic data components such as new query filters, entity templates, rich support for Entity Framework 4, and validation and templating capabilities that can be easily applied to existing web forms.
- Web forms support for new enhancements to the AJAX library, including built-in support for Content Delivery Networks (CDN).
- For a complete list of extensions for ASP.NET, see this link.
- Improvements in Windows Presentation Foundation (WPF)
- Added support for multi-touch, ribbon controls, and Windows 7 taskbar extensibility features.
- Added support for the Surface SDK 2.0.
- New controls for line-of-business applications, such as charting control, smart editor, data grid, and others, improve the productivity of developers building data applications.
- Improvements in performance and scalability.
- Improvements in text clarity, pixel snapping, localization, and interaction.
- For a complete list of WPF extensions, see.
- Enhancements to Windows Workflow (WF) that enable developers to more effectively maintain workflows. Includes an improved action programming model, an improved designer interface, a new style of flowchart modeling, an expanded action palette, workflow rule integration, and new message correlation capabilities. The .NET Framework 4 also provides significant performance improvements for WF-based workflows. For a complete list of extensions for WF, see.
- Improvements in Windows Communication Foundation (WCF), such as support for WCF Workflow Services, for creating workflows that support message-based action correlation. In addition, the .NET Framework 4 provides new WCF components such as service discovery, routing service, REST support, diagnostics, and performance. For a complete list of extensions for WCF, see.
- The latest parallel programming components such as parallel loop support, TPL (Task Parallel Library), PLINQ (Parallel LINQ) queries, and coordination data structures that enable developers to efficiently manage the capabilities of multi-core processors.

Microsoft .NET Framework is a digital platform that allows you to create, correctly launch and use various applications or games, when creating, parts of one particular application are written in different program codes. This platform is a digital environment in which different codes of a given application are compiled into one rolling code, which in turn is understood by the Framework itself. Then the rolling code is compiled into understandable code for the operating system itself, for which the application was developed. For example for Windows 7/8/10
You can install this platform in various ways.
- By installing an operating system whose service pack already includes that platform.
- Download Net Framework and then install. (Official links on our website)
- Install as additional software when installing the game.
- Install automatically using Windows Update
There are cases: When a game or application is launched, a window of approximate content pops up on the screen: “(application name) requires the presence. NO Framework. Please download and install Net Framework 3.5 or higher. " What makes the launch of this application impossible without this platform. If you have Microsoft Net Framework 4.7 installed, this does not mean that you do not need older versions. You will need to install both Microsoft Net Framework 4 and previous versions. It is highly recommended to install all existing ones regarding your operating system.
