Visual studio .net problem

Денис Швацкий 1

Hello.
I reinstalled windows 10. Installed visual studio 2022.

When start a project, .NET framework 4.0 is required

Error when installing .NET framework 4.0

Microsoft .NET Framework 4 is already part of this operating system. Installation of the .NET Framework 4 Redistributable is not required

How to start a project? Update it to last .NET framework?

Hello @Денис Швацкий , what kind of project are you going to start(create and develop)? Like what Castorix31 mentioned, did you choose and install the required workloads and components? Besides, please make sure you have updated Windows OS and there is no Windows Update error.

Visual studio was installed after all windows updates

I installed visual studio many times, with standard components, and everything always worked. But not now..

Hi @Денис Швацкий , please try to repair .NET Framework by using Microsoft .NET Framework Repair Tool and check again.

Please read the other answers: this has nothing to do with the framework itself and no need to repair.

Hi @EckiS , thanks for the reminder :) Previously I thought @Денис Швацкий was using a new project, and now I see. So the solution should be retargeting the existing project to a higher version of .NET Framework or creating/using a new project targets higher version of .NET Framework(with the target pack installed).

Hi @Денис Швацкий , if you are still having issues then it may be helpful for you. Visual Studio 2022 supports .NET Framework 4.6 to the upper version. So go to Visual Studio installer -->modify -->individual component -->select the required framework and install it(click Modify option). I would recommend the latest one. Then open the project and upgrade it to the available target framework that you have installed.

Have you installed ".NET Desktop Development" ?

Like in the picture :

To install the .NET Framework Developer Pack or Targeting Pack

There is no ".NET Desktop Development 4.0"

Have you checked ".NET Desktop Development" in the Workloads ?

this is not working.

Installation notes:

.NET Framework 4.5 and later versions replace .NET Framework 4.0. When you install these versions on a system that has .NET Framework 4 installed, the assemblies are replaced.

Could this be a problem?

You cannot check and install ".NET Desktop Development" ?!

And what is installed ?
commands like :
dotnet --list-sdks
dotnet --list-runtimes

This has nothing to do with installing the .NET runtime or Windows 10.
you don't have the target pack for .NET Framework 4 installed.
When you opened the solution you will have got a dialog like this:

and the option to download the target pack.

But .NET Framework 4.0 is no longer supported, so you need to target a newer version anyway (4.6.2 or higher).
