I'd like a system dump upon exception of all local variables (names and values) at the time of the crash. I wonder. This may require reflection, at which I am clueless.  
Any ideas?

What you probably want is to use a minidump (this is the standard way of doing this)

THAT is really wild stuff Greg.  I'm gonna have to read it a few times, but I think I'll use symbol server as well - to make the symbol load go smoother.  The question here is, (and maybe this is due to the brief example), does this thing display variable names and values as well?  The example only shows a call stack, which I already have with Environment.StackTrace.
Thanks

It is a full memory dump of your application .... you can inspect threads, look at memory/locals, etc etc.

Doing with .NET you will want to look up a tool called SOS (Son of Strike) as well...

http://msdn.microsoft.com/msdnmag/issues/03/06/Bugslayer/ and http://msdn.microsoft.com/msdnmag/issues/05/05/JITCompiler/default.aspx?side=true are worth reading (as is the whole bugslayer series which are generally by John Robbins). This is a huge topic ... so huge in fact that John has about a 1000 page book on the subject http://www.amazon.com/Debugging-Applications-Microsoft-Windows-Pro-Developer/dp/0735615365/ref=sr_1_13?ie=UTF8&s=books&qid=1195087368&sr=1-13 and http://www.amazon.com/Debugging-Microsoft-NET-2-0-Applications/dp/0735622027

in particular in http://msdn.microsoft.com/msdnmag/issues/03/06/Bugslayer/ look at Figure 2 (the output from !CLRStack, it shows you locals + parameters)
