Debugging managed code.. from a newb for managed code debugging

Debugging managed code in WinDbg has never been my idea of fun. I wasn’t forcibly exposed to it enough I guess.   For example, if you look at http://blogs.msdn.com/spatdsg/archive/2009/02/23/there-and-back-again-the-life-of-a-bug-and-fix.aspx   there is like a 5 step process for setting a breakpoint, instead of !bpmd.

Here is a snip from an older KB “… However, if you remove the paging file from the boot partition, Windows cannot create a dump file (Memory.dmp) in which to write debugging information…
