The requested operation cannot be performed on a file with a user-mapped section open

Question

Whenever I tried to copy 4 files into my bin folder, after stopping the main service, I am getting an error with one file (TexteDll). The error is:

Cannot co         


        

Answer 1

None of the solutions posted here worked for me. It was devenv.exe (Visual Studio) locking the file, but if I restarted it, it would re-lock it.

Bizarrely, Windows wouldn't let me Delete the files (to Recycle Bin), but Shift+Delete (permanent delete) worked.
