Thomas Lai is now blogging! Thomas works on the CLR Debugging Services, along with other bloggers Rick and myself and some non-bloggers too.

Thomas owns the MDA infrastructure, among other things, and has a great practical post about about how to deal with that annoying pinvoke MDA. Thomas worked on porting the CLR (especially the Debugging Services) to 64-bit and is the only one on the CLR debugger team (to my knowledge at least) that doesn't break a sweat when looking at ia64 assembly code. See his intro for more details.
