Debugging an application in VS works, but running the application doesnt, why?

What i mean is that i have a VS project. The project compiles and links properly. When i clic开发者_运维技巧k on "Start Debugging", the application runs and everything seems to be working.

When i go to the debug or release directory and try to run the application, I get a runtime error. Why does this happen?

I dont know how to word this to search in Google. Maybe someone can point me in the right direction.

Thanks

debuggers often do extra initialization of variables that otherwise will not occur at runtime. Or you debug environment includes a dependency that is not available when you run it independently of VS
