LINK error :(

You might need to change how the crt is linked into the debug version.

These might help.

C Run-Time Libraries
Linker Tools Error LNK2001
Linker Tools Error LNK2019

Assuming there are not many .lib files that you have included in your solution... you might find the following hit and try solution useful:

- Open up two instances of Visual Studio.Net.
- Open up the same solution on both IDEs.
- Goto Project-> Properties (for both).
- For one IDE open, select Release Configuration from top left drop down box, and for other, Debug configuration.
- Click Linker->Input. Open Additional dependancies (for both).
- [There should'nt be many files here], you can compare each file to see which is missing in the Debug configuration..

There is the possiblity error can be traced from here, as fstream that is in the error message should be included by VS.net by default (I assume), so, missing lib could be in the additional dependencies tab mentioned above.

Ofcourse, there are other places where the missing lib file could included in Release, and not in Debug configuration...above solution is worth a try.

And what about the C Runtime(crt)? That one of the link errors reads

unresolved external symbol "void *__cdecl operator new

suggests quite strongly to me that you haven't linked with the crt. Check out the "C Run-Time Libraries" link I dropped earlier. You might need to link with LIBCPMTD.LIB or MSVCPRTD.LIB when in debug mode.

I would favor the lib files that came with the PSDK and the VC Toolkit instead of the ones that you got from VC5. I would also keep a list of the ones from VC5 so that it's easier to replace them if the need arises.
