Auto-Generate ViewModel Class

Question

Hello , 
In my current project, we are using Silverlight 4, RIA services, Linq-to-SQL,MVVMlight from GalaSoft. I aware of creating .dbml file , domainservices.cs and doaminservice.metadata.cs files.But I am not aware of creating a viewmodel.cs file automatically.


This project is halfway done, all the viewmodel.cs files are auto generated. I dont know how to generate the viewmodel files automatically. I am trying to write the code manually, bu the problem is after rebuilding the code I have written is gone, or it is not taking any datacontext.

I am new to RIA services .Can anyone please help me out with this. Thank you very much.
