There are some components that we may never hear, or rarely hear, in Windows 10/11 but that perform special tasks in the background so that both the applications and the system itself can work in an integral way, and one of these is the .NET Framework..

 

.NET Framework is a runtime environment in which we find a group of libraries developed by Microsoft which allow creating and managing an environment for the development and execution of applications in the C# programming language, Visual Basic.NET and other languages. .NET compatible.

 

Components
The .NET Framework is made up of two main components which are:

 

  • Common Language Runtime (CLR): It is the execution environment of the .NET Framework and it contains services for memory management, garbage collection, exception handling, security, and more.
  • .NET Class Library (BCL): Refers to a collection of predefined classes, interfaces, and types to provide features for application development such as file management, cryptography, network communication, and many more.

 


 

A problem at present is that the .NET Framework may suffer failures, for which it will be necessary to repair it. TechnoWikis has a series of options to correct and repair the .NET Framework in Windows..

2 Repair the NET Framework by re-enabling the .NET Framework

 

Step 1

The .NET Framework is in Windows 10/11 as a system feature, so if it fails, it will be possible to disable it and then enable it again, for this, in the Start search engine, we are going to enter the word "features" and in the results we click on “Turn Windows features on or off”:

Step 2

In the pop-up window we will see the following:

In this window we will deactivate the following boxes:

3 Repair NET Framework from Console

 

In this case TechnoWikis will teach you how to use PowerShell or the terminal in case of errors, this will depend on the version of Windows used since the command may work incorrectly in one or the other-

 

Step 1

In the Start search engine we enter the word "powershell" and we will open it by clicking on "Run as administrator":

 

image

 

Step 2

In the terminal we will execute the following:
 Get-Package -Name “Microsoft .Net*” | uninstall-package 
image

 

Step 3

We enter the letter S to confirm the process, this will only be correct if a version of the .NET Framework has been downloaded directly from its official website but not through Windows Update:

 

image

 

Step 4

After this we are going to search for the packages related to the .NET Framework using the following command:
 winget search Microsoft.DotNet 
image

 

step 5

As we can see, a winget error occurs, for this we are simply going to open the Terminal by right clicking on the Start menu and then clicking on Terminal (administrator):

 

image

 

step 6

Now it's time to search for packages associated with the .NET Framework with the command:
 winget search Microsoft.DotNet 
image

 

step 7

There we enter the letter Y to confirm and we will see all the results associated with .NET:

 

image

 

step 8

To install .NET we are going to execute the following syntax:
 winget install [ID] 
image

 

step 9

In a moment the installer will open:

step 10

There then we will see that everything was successful:

step 11

We repeat this process with the versions that we want to install:

4 Repair NET Framework by resetting the PC

 

Step 1

Finally, if none of the solutions correct the error, we can restore the PC to its original values, for this we go to the route:
  • Start
  • Setting
  • System
  • Recovery

Step 2

Now we click on the "Reset the device" option:

By clicking there we will see the following:

Step 4

It is time to select whether or not to keep the files, then we define the installation mode to use local or in the cloud:

step 5

You will have a small summary of the action to be taken:

step 6

We click Next to start the process:

step 7

Then at the end of this we will click on the "Reset" button:

step 8

We must wait for the process to be completed to have the .NET Framework functional.
These options will help us to recover the correct functioning of the .NET Framework in Windows and with it an optimal execution environment.
