As far as I know, Visual C# doesn't have dumpbin utility, it is shipped with Visual C++ (not sure if it is included in VC++ Express Edition), you can find it in the "bin" directory.
dumpbin.exe is a part of the Visual C++ tools. The Express edition of Visual C++ includes it. Once you have installed Visual C++, it will be available in C:\Program Files\Microsoft Visual Studio 8\VC\bin.
dumpbin.exe
