What is Microsoft.NET Framework. How to install and reinstall NET Framework? Installing or updating, fixing errors Installing net framework 4 on windows 7

I was able to solve the problem, but before that, all the official programs for searching and fixing the Windows 10 update center ver. 1607, as well as various scripts The forums didn't help.

RESTORING STORAGE FROM THE ORIGINAL WINDOWS IMAGE HELPED:

INTERNET IS DISABLED.

1. I found the official original image and downloaded it, I have Windows 10 for one language, ver. 1607.

2. copied the image to HDD- I have not system disk D.

3. I unzipped the image with Winrar and found the file insnall.wim (INSNALL.ESD - WILL NOT WORK) in the sources folder and copied it to the root directory of the disk D .

4. executed on the command lineWindows PowerShell running as administrator:

PS C:\WINDOWS\system32> Dism /Get-WimInfo /WimFile:D:\install.wim

C DISM system

Version: 10.0.14393.0

Image details: D :\install .wim

Name: Windows 10 Home Single Language

Description: Windows 10 Home for one language

Size (bytes): 14,047,031,800

The operation was completed successfully.

! The Windows 10 Single Language image is located at index 1

5. Restored the storage:

PS C:\WINDOWS\system32> Repair-WindowsImage -Online -RestoreHealth -Source D:\install.wim:1

Path:

Online: False

ImageHealthState: Healthy

RestartNeeded: False

PS C:\WINDOWS\system32>

My restoration operation took about one hour.

6. Just in case, I ran the script:

7. Rebooted the computer and manually started the search and update, Microsoft update.NET Framework 4.7 for Windows 10 Version 1607 and Windows Version Server 2016 for 64-bit systems downloaded quickly enough, installed and asked to restart the computer to complete the installation of the update.

8. Rebooted the computer and that’s it.

Microsoft .NET Framework- this is the so-called software platform. Installation of the NET Framework is required to run programs written on this platform. To make it clearer for you, I will explain it as follows: some video files will not play in Windows if the necessary codecs are not installed for them. The situation is the same here: programs written for the NET Framework will not be able to execute if this component is not installed on the system.

An important point: for an application written for a specific version of the NET Framework to work, this version must be installed.

Microsoft released the first version of the NET Framework back in 2000, and since then several have been released (NET Framework 1.0, 1.1, 2.0, 3.0, 3.5, 4.0, 4.5).

How can you find out which NET versions Framework installed on your computer?

Microsoft .NET Framework 4.5.1
It is an update to versions 4.0 and 4.5, so if you are installing 4.5.1, then these versions do not need to be installed. Windows XP is not supported by NET Framework 4.5.

How to reinstall Microsoft .NET Framework?

Sometimes problems arise in the system, one way or another related to the NET Framework. For example, errors appear when starting some programs or when installing (updating) the Microsoft .NET Framework itself. In this case, the most reliable solution to the problems is to remove the platform and reinstall it.

To correctly remove NET Framework from your computer, it is best to use a program specially created for this .NET Framework Cleanup Tool.

Download it, then unpack the archive and run the file cleanup_tool.exe.

A message appears: “Do you want to run the .NET Framework Setup Cleanup Utility?” (though in English) – click “Yes”. Then accept the terms license agreement(“Yes” button).
In the program window, select “.NET Framework – All Versions” from the list and click the “Cleanup Now” button:
After uninstalling the NET Framework, restart your computer. Then reinstall the versions you need, starting with the smallest one.

Kit system libraries The Microsoft .NET Framework 4.7 provides many services, including memory management, environment security, security policy functionality, network deployment tools, and robust mechanisms for applications to function properly.

It provides easy-to-use data structures and user-friendly APIs for creating complex software products. For programmers, this provides ample opportunities to write program code in high-level programming languages such as Visual Basic, C#, F# and many other advanced development environments.

You can download .NET Framework 4.7 for Windows OS for free from our website or the official resource of the developer company.

.NET Framework 4.7 is a complex platform that is used in development software for the Windows OS line (the same name was no exception mobile platform for smartphones and tablets). It consists of a CLR (Common Language Runtime) environment and a special class library that includes a wide range of functions and support for many industry standards.

Some versions of the .NET Framework come with operating updates Windows systems, however, modern software may require the installation of a more recent version of the framework - .NET Framework 4.7, which will allow you to run the necessary software without errors and “ blue screens of death".

What's new in version 4.7?

Besides everything else, Windows exit 10 pushed the .NET Engineering team to release a fresh version of the .NET Framework, the version of which received the serial number 4.7.

In addition to improved performance and reliability, 4.7 takes advantage of the new Ten, High DPI support for Forms applications, support for WPF touch applications, expanded cryptography support, and support for TLS protocols.

10's support for high DPI devices means that the .NET Framework 4.7 can render Forms applications at higher DPIs, from icons to glyphs and layouts, and even when moving applications to different DPI monitors and devices.

NET Framework 4.7 also supports dynamic DPI. For example, when software is running on one device, the program may respond dynamically if it is moved to another monitor. It should be added that version 4.7 is already part of the Windows 10 Developer Update and does not require installation.

This release comes with new features that developers can use in their programs. While there is no immediate need to download and install a new platform, once developers and companies start releasing products targeting new version, you will need to download this version.

Operating system support: The update package in the form of .NET Framework 4.7 can be installed on Windows 7 and higher, as well as on servers ( Windows Server 2008 R2 SP1).

- New developments in Visual Basic and C#, such as lambda operators, implicit line continuations, dynamic dispatch, and named and optional parameters.
- Improvements in data access and modeling.
- Extensions in ASP.NET
- Improvements in Windows Presentation Foundation (WPF)
- Enhancements to Windows Workflow (WF) to help developers maintain workflows more efficiently. Includes an improved action programming model, an improved designer interface, a new style flowchart modeling, an expanded palette of actions, integration of workflow rules, as well as 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.
- Enhancements in Windows Communication Foundation (WCF), such as support for WCF Workflow Services to create workflows that support message-based activity 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, allow developers to efficiently manage the capabilities of multi-core processors.

Microsoft .NET Framework is a digital platform that allows you to create, launch correctly and use various applications or games, during the creation of which parts of one specific application are written in different program codes. This platform is a digital environment in which different codes of a single application is compiled into one running code, which in turn is understandable by the Framework itself. Then the moving code is compiled into understandable code for the operating system for which the application was developed. For example for Windows 7/8/10

You can install this platform in various ways.

Having installed operating system, whose update package already includes this platform.
Download Net Framework and then install. (Official links on our website)
Install as additional software when installing the game.
Automatically install using "Center" Windows updates»

There are cases: When starting a game or application, a window with approximate content pops up on the screen: “(application name) requires the presence of. NO Framework. Please download and install Net Framework 3.5 or higher." What does startup do? 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.
