Updating versions in mixed projects

[benfulton]

I have a VS.NET solution file I am compiling with Visual Build. The file has some C# projects, and they update versions correctly, but it also has a C++ DLL in it that does not seem to have its version incremented. In the project I always see

Post-processing...
DicomPing.vcproj...(no changes)
Implementation.csproj...incrementing version...
Interfaces.csproj...(no changes)
Watchdog.csproj...incrementing version...

even if the vcproj has changed.
