Adding classes to project template at runtime in Visual studio 2010 extensibility

Hi,

I am creating Custom Test Project Template using Visual studio 2010 extensibility.

I have to add multiple classes to project template at runtime based on different classes selected for different methods for test case generation.(As like Unit Test Wizard in Visual studio 2010).

I searced lot on internet but not able to find solution for this problem.

Please help me to solve this problem.

Thanks in advance!!!

Kind Regards,

Ganesh Gidde.
