Crack.NET is a runtime debugging and scripting tool Josh Smith made that gives you access to the internals of any .NET desktop 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, inspect all kinds of values on objects, and even manipulate those objects via IronPython scripts.
