Did the project build successfully? Can you find the exe in the local folder?
You can such an error when the application was started from debug/relase bin folder and is still running; then the EXE is locked and the build process can't replace it.
Lookup in Task Manager if the EXE is running.
That was truly the problem i just had to close the port it was running at and the re build it. Thanks brother
