[Python.NET] Problem debugging to python.runtime.dll

Hi, We are actually using Python.Net with python 2.5 and I wanted to learn the internal architecture of the Python.Runtime.Dll. I have tried debugging the dll by attaching the process to python.exe but doesn't hit any break point. I don't know much about the compiler design and how it works internal but all I want is I should be able to debug how my C# instruction is getting executed using python.runtime.dll It would be really helpful if I get steps to debug it or get some sort of direction or architecture design diagram. Thanks and Regards, Vishal
