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

You probably have deactivated the debugging information for your project:

• Right click on your project -> Properties
• Configuration properties -> Linker -> Debugging
• Switch "Generate Debug Info" from No to Yes

Rebuild your project and retry, it should now run without the message :)

Answer 2

Restarting Visual Studio can fix one instance of this problem.
