I wasn\'t sure how to word the question but I would like to step through code as it goes through the .NET classes/methods, etc.
Earlier I had asked about how to view
In Visual Studio .Net 2008 select Tools->Options and tick Debugging->General->Enable .Net Framework source Stepping.
You'll need to be connected to the internet so the symbol files can be downloaded.
Yes, use the debugger, but see Configuring Visual Studio to Debug .NET Framework Source Code.
