Crack.Net by Josh Smith

Catchy name for a debugging tool :)

Ever needed to fix a bug that didn't happen on you development machine, but does in test (or production, but the disclaimer clearly states not to use it in production ;) well now you can try this new tool. It injects itself in a running .Net application and allows you to browse and change the objects in the managed heap of that _running_ application.
