Visual Studio不会打开C＃项目

Question

Starting from yesterday, whenever I try to open a C# project (.csproj) in visual studio
I get this 3 times:

And then I get this 1 time:

And thus it doesn't open the project.
This doesn't appear when opening C++ or VB projects, only C#

I have tried running the application with parameters like /resetsettings and /resetskippkgs but it didn't do.

Please help me solve the problem

Answer 1

Your Visual Studio install has become corrupted. Reinstall Visual Studio ("Repair" should work ) and it should fix itself.

Answer 2

1. Reinstall VS.
2. Try to open another project and see if you can open it, if it opens, copy the source files to the new project and continue as usually.
3. What version of VS are u using?
