public static void Test()

Any public method by rightclicking on the header and selecting "Run test".

Just leave your callback....
Why should a callback be static?
You get the specified error because you are accessing CommSocket which is a member of the class .
CommSocket must be static as well if you are trying to access/manipulate it from a static method .

Taken from
The Life And Times of an ASP.NET MVC Controller .
