How to get the Assembly Name of Calling Application.

Question

Hello All,

       I have a solution that has around 4 web projects attached. consider Project A, B, C, D Respectively (ASP.net/C#), Here Projects A,B, C are not interrelated. Only relation will be A to D, B to D, C to D. 

• In project A, Project D is referenced.
• In Project B, Project D is referenced.
• In Project C, Project D is referenced.

Some where in Project D , i want the application name or assembly name , from where the control has come, ie either from Project A, or from Project B or from Project C.

I tried reflection, but i get only the details of Project D.

Please help guys !!

Thanks
