Line numbers and parameter values in browser error messages in Silverlight

Question

So far i have not found any solution to this problem. There are many questions about this when i google it, but none of the discussion ends with some conclusion. I want to have line number in stack trace whenever an exception is thrown in silverlight application.

Something like this:

System.NullReferenceExceptinon 

  SL runtime method without line number: OK

     my method1 without line number   <--- how to show line number ?

        my method2 without line number   <--- how to show line number ?

Regards.
