Nobody's got any advice?
Well, I've been poking at it some more and I'm pretty convinced that the
problem is that somehow I've lost the symbols for the entire .NET Framework.
I finally found the Modules window: Debug -> Windows -> Modules. But
nothing shows up there unless the application stalls for some reason.
(I'm lucky, I guess, because I have another ([un]related?) problem where
running the app from F5 loads a browser window which tells me that the
server cannot be found. Reload brings up the page every time, as does
going to the url outside the debugger.) Normally, it appears that
stopping on a breakpoint would accomplish this, but since the problem is
that my debugger won't stop on breakpoints...
Anyway, when I try to manually reload the symbols, I can't find
mscorlib.pdb (or .dbg), or any of the other symbol files, anywhere on my
system.
So before I bite the bullet and reinstall VS.NET 2003, can somebody at
least answer these questions:
1) What is the symbol filename for mscorlib.dll? System.web.dll? Etc.
2) Is there some way to reinstall the symbol libraries other than
reinstalling all of the .NET framework and VS.NET?
