I am working on a Managed C++ project and I get the following error:

TestThread.cpp(3) : error C2859: c:\projects\ProjectName\debug\vc70.pdb
is not the pdb file that was used when this precompiled header was
created, recreate the precompiled header.

Why would I get this error? How do I rebuild the precompiled header?
Clean Solution, Rebuild Solution, don't help.

If I manually delete the vc70.pdb, it doesn't seem to recompile. I've
also tried manually compiling stdafx.cpp. I get:

fatal error C1083: Cannot open precompiled header file:
'Debug/ProjectName.pch': No such file or directory

Any help is appreciated.

Managed C++ gets more and more frustrating every day.

This should not be caused, I think, by your use of MC++. Seems like your
project settings got hosed somehow. First, try if you like to disable
precompiled headers (it's in the compiler options in the project settings).
See if that helps at first. If it does, then try setting your settings for
stdafx.cpp to "Create precompiled Header" (/Yc) with stdafx.h, and then set
the rest of the files to "Use Precompiled Header" (/Yu) with stdafx.h. See
if that helps

(man I hope I got this one right, it's been a while since I've fiddled with
those :))

That resolved the issue; I removed all files and started adding them
back in slowly, and didn't properly reset stdafx.cpp to "Create
precompiled header".

You're right, this wasn't related to .NET or MC++. At least I'm one step
closer to getting this stuff working. Thank you!
