web deployment - Azure web deploy/publish keeps getting stuck -

every time try publish web app azure gets stuck, how can determine problem is? logs etc, cant see output thats not enough diagnose issue.

so way got around issue set visual studio parallel build settings 1.

this force visual studio build each individual project 1 after other, , way able diagnose if there going wrong during build stage or not.

fortunately me nothing wrong build stage , project got published fine.
