Error in the using namespace for bin directory

Hi All,
I am trying to run a application, but while compiling I am getting an error, I am not able to run the application.

Error details:
See the image.

Thanks in Advance.

The error message is telling you that no such namespace exists, so you cannot import any such namespace. 'bin\Debug' is the output folder when building in the Debug configuration so why would there be such a namespace? Why exactly do you think you need to import it?
