Question

This error is thrown when I try to debug Application on Visual Studio 2013.

Here is Stack Trace.

Seems like a process blocking that file. Have your tried to restarting Windows? — Daniel Manta
@derloopkat I solved this error by restarting the computer then delete csc.exe from rosyln folder. — TAHA SULTAN TEMURI

I encounter the same problem randomly and found the easiest way to get around it by:

Right click the solution and go to properties
Change the value of the Output path from bin\ to bin1\

now build and I hope it will work
