NET Framework (Dot Net Framework) is a software platform (software framework) developed by Microsoft Corporation in 2002, mainly for operating Microsoft systems Windows. Includes extensive libraries, and also provides cross-compatibility (each language can use code written in other languages) of several programming languages. Programs written in the .NET Framework run in a software environment (as opposed to a hardware environment) known as the Common Language Runtime (CLR), which is a virtual machine, which provides security, memory allocation, and exception handling. The class library and CLR together make up the .NET Framework.

The core .NET Framework class library provides access to the user interface, data communications, database connectivity, cryptography, web application development, computational algorithms, and network connections. Programmers create their applications by linking their own code with the .NET Framework libraries as well as other libraries. The .NET Framework is intended to be used by most new applications being developed.

ATTENTION: Be sure to install the update packages in the same order in which the links to them are given!

Microsoft .NET Framework is a technology aimed at creating various utilities and applications. This package is required for the functionality of applications developed on the .NET architecture. You can download net framework 3.5 on our website.

NET is interpreted by a built-in component of the Windows OS that supports the development and execution of the latest generation of applications and web services. The main components of the .NET Framework are the implementation area on a common language basis and the .NET Framework class library, which includes ADO.NET, ASP.NET, Windows Forms, and the Windows Presentation Foundation. The .NET Framework has a manageable implementation scope, the ability to simplify creation and deployment, and the ability to integrate with a variety of programming languages.

Keep in mind that the latest version of the .NET Framework rarely updates its predecessor. This means that if the user, for example, has 4.5, but does not have 3.5, and the program needs the old one, then it will not launch. To ensure compatibility with the largest number of programs, installation of all available versions of the framework is required. You can find out more about all versions on the official website.

But if, in the event of a problem, even installing the required version did not help, then you should update other components, without which many programs and games will not start. One of them is a package of libraries, which is necessary for running applications that use 3D graphics. Without it, when you try to start, a message usually appears that a file with the “dll” extension is missing.

Valuable Mentions:

• In general, it is not advisable to remove any versions of the .NET Framework installed on your computer. Various types of applications are dependent on different versions, while it is possible to download a number of versions of the .NET Framework in parallel on one computer.
• The .NET Framework 3.5, in turn, is used by applications developed for versions 2.0 and 3.0.
• Installing the package Windows languages Before installation, .NET Framework 3.5 may cause the installation of .NET Framework 3.5 to fail. When installing .NET Framework 3.5 after Windows Language Pack, an error appears.
• Unfortunately, the difficulties associated with installing the .NET Framework 3.5 prevent the use of a separate standalone installer that can perform the implementation without depending on Windows Update. Provided that the remaining methods end in error, you need to use the installed media, as shown above.

How to remove Microsoft .NET Framework and then install another version? This happens extremely rarely. At times, the required version of the NET Framework has been installed, but the utility still does not launch, and various types of errors are displayed. In such a situation, it makes sense to uninstall earlier installed platform NET Framework and install a new one. You can download net framework 3.5 on our website using the link below.

• Allows developers not to waste time working out the interaction of the created product with the environment in which it will be executed (be it hardware characteristics, compatibility, OS features or other technical aspects of the environment).

• Can work with many programming languages ​​using a set of special algorithms, which gives application creators the opportunity to use almost any known design principle program code for your software.

System requirements for optimal performance of the .Net Framework

Requirements for hardware components for normal operation .Net Framework low enough that the component will work even on the weakest computer. The rest of the information in this chapter is primarily intended for first-time users.
Those more advanced can skip to the chapter where you will learn about. Your computer is required to:

• Processor frequency 1 GHz and higher;
• Volume random access memory no less 512 MB;

• Windows Server 2016, 2012 and 2008.

Download .Net Framework 3.5 (including versions: 3.0 and 2.0)

NET Framework is evolving, and newer versions may lack some components that were previously present in older versions. earlier versions.

This happens for various reasons: some components could become outdated, become no longer relevant, or they could be replaced by new, more advanced components of the Framework. Some older applications may require exactly those old components that are missing in new versions, which requires installing one of the older versions of the MS .NET Framework. Version 3.5 already includes minor versions of libraries (so there is no need to download them separately):

• .Net Framework 2.0;
• .Net Framework 3.0.

Errors during installation or operation of the .Net Framework

This is most likely due to the fact that some Windows updates may not be tested to work or interact with the .NET Framework 3.5 installer.

MS developers assumed that users would use new, more current versions of the Framework, and the .NET Framework 3.5 installer itself was created long before these updates, and does not take into account the changes in policies and security mechanisms that they bring.

To use .Net Framework 3.5 (and below) on new OSes, you must:

1. Temporarily disable "Windows Update";
2. Delete KB2966826 And KB2966828 through standard remedy"Installation and removal of programms";
3. Restart your computer and repeat installation .Net Framework.

After installing the component, you can turn it back on automatic updates.

Selecting the hard drive and folder to extract .NET before installation (the installer can choose the drive, for example drive A:)

The installer of the latest versions of the .NET Framework selects the destination drive and folder at its discretion. This may be a rather non-obvious choice, for example drive A:, or another drive not intended for these tasks.
To get around this problem, just run the installation using command line(see Figure 5): Figure 5. Installation of .NET Framework 4.7.1 with unpacking into a specific folder.
