How to give Visual Studio a bream and make them change their minds about a project?

Question

C++ / C#

Hello!
Something is wrong - VS either sees that the class is declared twice and sends it to the same place, then it looks for the class in another place where it has long been gone.
I've tried clean solution and rebuild solution but it doesn't help.

Answer 1

She is looking for him everywhere, and not where you want, it seems. You need to give this bream that you are skipping classes.

Answer 2

Clean up the bin and obj folders, restart the studio. If not, look for the reason in the code.
