I found a link tonight that led to a Codeplex project http://www.codeplex.com/cracknetproject.
From the Codeplex site
Crack.NET is a runtime debugging and scripting tool that gives you access to the internals of a WPF or Windows Forms application running on your computer. If you love Snoop and Mole for Visual Studio, you’ll love Crack.NET, too. Crack.NET allows you to “walk” the managed heap of another .NET application, and inspect all values on all objects/types.
This looks like a good tool in becoming familiar with what is going on in WPF and Winform apps.
