debugging information cannot be found or does not match visual studio's

Question

I copied an existing project and renamed the folder. Now I get this error when I try to compile the application

debugging information cannot be found

Answer 1

I faced the same problem and tried all above mentioned solutions but it couldn't help me. Then I found a new solution randomly and it worked.

Solution is that,in case you are having many projects in a solution then you should mark any one (specific one which you have to decide) project as a "Set as Startup Project". Right click on that specific project and click "Set as Startup Project".

It worked for me.
