Go to Tools->Options->Debugging->General and see if the option "Use Managed compatibility mode" is selected. If it is, uncheck it and try again.

Hello,
I just installed Visual Studio 2019 onto my laptop and I can't run or debug anything since I installed the program. I am assuming I have nothing in my "solutions". Is that why nothing is working? I appreciate if someone can guide me to fixing this error.

the program, indicates that you are trying to build a
C# (C Sharp) program. You have posted your question with
the C++ "Tag". You should remove that Tag and add the
dotnet-csharp Tag instead.- Wayne

مقصود احمدی 0 Reputation points2024-01-27T13:57:11.5466667+00:00 Hello, I have just started web programming and I am writing a program with Visual Studio, but whatever I do, the project does not run. The first time I tried to run the project, it shows a box saying do you trust the program or I clicked no.
