Framework version 4.0.

Microsoft .NET Framework Overview

The .NET Framework is Microsoft's comprehensive and consistent programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of business processes.

The Microsoft .NET Framework 4 redistributable package installs the .NET Framework runtime and associated files that are required to run and develop applications to target the .NET Framework 4.

The .NET Framework 4 works side by side with older Framework versions. Applications that are based on earlier versions of the Framework will continue to run on the version targeted by default.

NET Framework 4 includes the following new features and improvements:

• Improvements in CLR and BCL
• Improvements in ADO.NET
• Enhancements to ASP.NET
• Improvements in Windows Presentation Foundation
• Improvements to Windows Workflow Foundation and Windows Communication Foundation

The .NET platform, developed by Microsoft, is an integral part of most games and programs that run on Windows OS. In the user's understanding, the .Net Framework 4.5 and 4.0 represent the basis for running programs in the development of which this platform was used. It has become a standard for developing web applications, so without it, there is a high probability that you will encounter problems with their operation. In addition, missing files for the required version of the .NET Framework may prevent games from running.

Starting with Windows 7, this platform comes bundled with the OS distribution, but a separate installation may be necessary if the required version is not available on the computer, or the .NET Framework fails.

Program versions

The most common and necessary 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 launching games and programs.

How can I find out which versions of the .NET Framework are installed on my computer?

This can be done in two ways:

1. Download and run ASoft .NET Version Detector from the official developer website.

1. Look in the system registry. For this:
   • run registry editor via Start – Run – regedit;
   • open the section HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP;
   • The names of the branches correspond to the installed versions.

.NET Framework 4.5

This version comes with Microsoft Visual Studio 2012. To install it separately, just download the .NET Framework 4.5 distribution for free from the official website and follow the installation instructions.

NET Framework 4.5 is typically not available by default on Windows 7 and must be downloaded manually. For this:

• Download .NET Framework 4.5 from the official Microsoft website

• Follow the web downloader and installer instructions.

The installation process is extremely simple, but it is important to remember that Earlier versions of Windows (XP and below) do not support .NET Framework 4.5.

.NET Framework 4.0

The previous version of the platform, which is automatically supplied with the Windows 7 OS distribution. Despite the update to version 4.5, it is still relevant. Most applications run smoothly with .NET Framework 4.5, but some may still require an older version.

Also, you will need version 4.0 if your OS does not support version 4.5.

The installation process is just as simple:

• Download the web installer from

The Microsoft .NET Framework is a software framework that supports the creation and execution of other desktop and web applications on Windows OS since build 98.

The main focus of this platform is the compatibility of various applications written in different programming languages.

Downloading and updating the Microsoft .NET Framework is recommended for those Windows users who experience errors during the installation of any programs or games.

Platform features:

• allows you to achieve compatibility between services written in different languages ​​and environments;
• independently take care of basic security, memory management and the list of exceptions while working with programs;
• identifies and loads only those components that are applicable and necessary for a particular system;
• does not require any settings from the computer user.

The purpose of creating the Microsoft .NET Framework was to give developers of various software maximum freedom of action for their creativity.

The Microsoft .NET Framework allows most programs to run on modern Windows operating systems. Therefore, its installation will be necessary for all users. Microsoft, starting with the Windows 7 operating system, has included this tool in the distribution and installs it automatically during installation.

Download NET Framework 3..

It was decided to entrust the mission of compatibility of applications of various types to this software environment without worrying about the language in which a particular utility is executed, its architecture, system bit depth or assembly.

The principle of completing the task in stages:

1. Start a service or process.
2. The compiler converts the language being used into a single bytecode.
3. Execution or translation of code for a specific target process or service.

You need to understand that the latest version of the Microsoft .NET Framework does not replace the previous one in all cases. It is also important that new builds of Windows operating systems do not support older versions of this tool.

It is recommended for all users of Windows 7, 8 and 10 OS of any bit size to update to the latest version of the Microsoft NET Framework.

So, if 4.0 is installed, but not 3.5, and the program needs exactly the previous one, then it will not start working without the necessary one. At the same time, 3.5 already includes 2.0 and 3.0, so sometimes it is better to install it. And XP from Microsoft supports software platform only up to 4.0. Therefore, when installing, for example, a game that requires a new version of the Microsoft .NET Framework, you will have to reinstall the entire OS or look for another alternative to the game.

It is worth noting that Microsoft does not recommend that users install multilingual versions of this software environment on their PCs. In such cases, conflicts and incorrect operation of utilities are possible. If the need arises, it is better to remove the already installed one and install a new one.
