I am encountering an issue that seems identical to this one .
I have a VS 2008 solution that includes, among other things: (names changed for simplicity)
When I build the EXE, VS gives me an error:
error CS0246: The type or namespace name 'Wrapper' could not be found (are you missing a using directive or an assembly reference?)
However:
The first linked question mentions something about a "duplicate definition of a compiler symbol", but I'm not sure what to look for in that sense.
Any ideas for what to try?
I think I figured this out.
Some more background: before building, the entire solution is created using CMake. I use CMake to make some edits to the csproj file for the EXE to point it to the correct references, including DLL B.
Whenever I run CMake, the statically defined GUID for DLL B in the ProjectReference node of the csproj file gets out of sync with the newly generated GUID for the vcproj that outputs DLL B. This GUID mismatch causes DLL B not to be referenced at build time , even though it shows up in the list of references and there are no related warnings or errors.
The way I discovered this was by looking at the build output. In the call to csc.exe, there was no '/reference' entry for DLL B.
Now I need to find a way to keep these GUIDs in sync!
