VS 2022 can not open .NET 4.7 C# solution on a newly installed Windows 11 machine

Question

I'm trying to open a C# solution with target Framework .NET 4.7 on a newly installed Windows 11 machine with VS 2022.

When opening the solution, the following message is displayed:

I the target version can not be changed.

I tried to install .NET 4.7.2 from here, reopen the solution, tut the same message is displayed.

dotnet --info command line result:

Please advise

The dialog actually **offers** to download and install the proper .NET framework version (second option) - have you tried that? And btw: the `dotnet` command line tool is **only** for .NET Core frameworks - it does **NOT** show/handle/detect the "old" full .NET frameworks installed or present — marc_s, Jun 24 '23 at 19:42

In the direction of @Tudeschizieuinchid answer. Trying to install v4.7 AFTER 4.8 was isntalled (as part of the vs installation), fails.

The way is to modify visual studio 2022 installation (or actually do it during the initial process).

Select .NET Framework 4.6.2-4.7.1 development tools option
