NET Framework is a programming model created by Microsoft in order to create software With good quality, with an attractive interface and sufficient security. This is an integral part of some applications, which has functionality for launching them.

The main idea of ​​this platform is compatibility various programs which were written in different languages programming. And also, what was written for netframe can be used in other environments besides Windows.

Microsoft NET Framework consists of 2 parts:

1. The performer's environment.
The multilingual Common Language Runtime (CLR) is the core of the platform and the main component of the system that manages the execution of user programs.

2.The Framework Class Library (FCL) which gives programs access to the runtime environment. It has a lot of elements for managing networks, databases, files, and interfaces. Developers need all this for programming.

Many users are interested in how to download NET Framework versions 3.5 for Windows 10 and why they can’t do it. And as usual, it’s worth paying attention to the computer requirements; the newer the framework version, the more specifications it needs.

NET Framework 3.5 includes new builds to enhance the capabilities of earlier NET platforms. It also has Service Pack 1 (SP1), which updates assemblies located in the platform itself.

In principle, all versions can be installed regardless of those that came out later, and each version automatically adds earlier versions if you have not installed them yet. You can also see in version 3.5 the Client Profile installation package, which includes assemblies of used client applications.

Windows 2000 does not work with the 3.5 framework and with a standalone installation.

Additional features in .NET Framework version 3.5:

• Using Windows Communication Foundation (WCF) technology, support for applications on portable devices has been expanded.
• Adding language tools (LINQ, new APIs)
• New compilers for C# have been added, Visual Basic, C++ and J#;
• Improve debugging with diagnostic tools
• You can now add graphics to controls
• ClearType font support
• It is now possible to change the BackColor property of read-only controls
• Maintaining SelectionStart and SelectionLength properties
• And much more

How to install NET Framework

If you have a Windows OS, then you most likely already have some version of the NET Framework installed. But not version 3.5, it is not installed automatically and you need to download it yourself.

This can be done in two ways:

1. Download installation file, which will download files from the Internet for installation. Moreover, its weight will be only 2.8 MB. And the file size depends on your OS.
2. If there is no option for online installation, then try downloading the full package, its weight is decent, about 200 MB, but you can install it offline.

Windows 7 and 8.1 systems must be installed with an integrated version 4.5 of the .NET Framework software platform, which is necessary for the full operation of some programs and games. And Windows 10 must initially contain a pre-installed version of the 4.6 platform, compatible with its predecessor version 4.5. The old version of the .NET Framework 3.5, which is required for the operation of programs and games that are usually not supported by developers for a long time, is included in current versions Windows is not included. Naturally, this means that the operating system was installed from the original distribution image. With non-original distributions, everything may be different: the operating system may either contain several versions of the .NET Framework, including the old 3.5, or come without separate pre-installed system components cut down type Windows builds.

The old .NET Framework 3.5 is installed as a separate step when installing programs based on the architecture of this version of the platform into the system. The installation of the latter can also be started manually by the user. What needs to be done for this? Open the control panel. In the latter window, look for the “Programs and Features” section. To make it faster, in Windows 7 the partition name can be entered as search query in the search bar of the Start menu. And in Windows 8.1 and 10, direct access to this section is provided in the menu called up with the Win+X keys. In the window that opens, click the link shown in the screenshot below.

A small window will appear with a list of system components. Here you need to activate the .NET Framework 3.5 version checkbox and click “OK”.

However, the process of downloading and installing the platform will not end successfully in every case.

How do I resolve problems that may arise during the installation of the .NET Framework 3.5?

1. Download the installer from the Microsoft website

If .NET Framework 3.5 does not install using the above method, you can try to solve the problem by running the platform installer downloaded.

2. Start the Update Center service

Platform installation error 0x800F081F is usually a consequence of disabling the Center service earlier Windows updates. If you disconnected system updates or, perhaps, special tweaker programs were used in Windows 10 for these purposes, you need to start the Center service. The System Services section can be opened using the Run command. Enter in its field:

At the very bottom of the list of services is the Center service. Double click to open it.

Let's start the service. Applying the changes.

After this, you must try again to install the platform using any of the methods discussed above.

3. Using DISM

The methods discussed above for troubleshooting problems that arise when installing the .NET Framework 3.5 require an Internet connection. If there is no Internet connection, you can use the Windows distribution to install the software platform. The method discussed below is also suitable for cases where, when trying to install the platform, you receive an error message 0x800F0906.

We connect the distribution kit of the version of Windows that is installed on the computer. Either we connect a flash drive, or insert a DVD into the drive, or mount the ISO image into a virtual drive. Windows versions 8.1 and 10, among the standard functionality, provide the ability to mount ISO images and display them as disk partitions. For this purpose in context menu On the Windows distribution ISO file, you must select “Connect”.

Before further actions, you need to establish how the distribution media is listed in Explorer. Then in command line paste the copied command:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:\sources\sxs

We edit the command: instead of the drive letter D, as in the example given, we substitute our own drive letter, DVD drive, or mounted ISO image. Press Enter.

After the command execution progress reaches 100%, we can close the command line and try again to install the platform using the method described at the beginning of the article.

Have a great day!

Surely many have heard about Microsoft .NET libraries, which are often the core of various applications. The interaction between the software that uses it and the libraries themselves is carried out through system components of the .NET Framework. Without them, many applications simply will not install.

The situation is different with the already outdated version 3.5 . It was widely used in Windows times 7 and is not compatible with .NET Framework 4.x. Since version 3.5 is not included in Windows 10 by default, many older programs simply will not install.

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.
