Felice Pollano has just released the first version of the new Deblector addin for debugging within Reflector. It’s only alpha at the moment and has some obvious bugs but it is very promising. In the past I have looked at having a Virtual PC with a hacked rebuild of the core framework with debugging enabled. Now I can step into framework code just as easily within the familar Reflector interface. I don’t have much experience with IL so I was a little confused at first when multiple lines of IL seemed to execute at once but I quickly realised they all applied to method call setup. I suspect, if possible, we may even be able step through the framework viewed in our chosen language. Keep an eye on this one.
