Do you know who Tess Ferrandez is? If not, you are missing out on the author of what I consider the most lucid series of articles on the topic of debugging .NET. Check out her series of demos on how to fixxit all things .NET . The most useful post I have seen so far is her piece on how to capture dumps on 32 bit process within 64 bit systems (without needing to DL procdump). +1 nerd points to Ms Ferrandez for making my job of learning all things Windows a bit less painful.
