How can I debug Just My Code? [.NET]

"Sometimes developers want to debug just the code they wrote and not the 3^rd-party code (such as framework and libraries) that’s also inside their app. This becomes particularly useful when user and non-user code call back and forth between each other. The v2.0 CLR debugging services have a host of new features to support this, which we call “Just-My-Code” (JMC) debugging."

Yup, seems quite useful. Have the complete story here.
