I did what you had suggested but atill the problem
persists.I really dont know what can be wrong.Its
strange I open other Projects and the Debugger works
fine

Hey One more thing I noticed now is that I cut Coied
and pasted the DLL from the Bin directory to other
folder on the desktop now when I debug  my project
without the DLL in the Bin directory the DLLs are
placed back Automatically in the Bin directory after
Building the Project
