Prebuild event in Visual Studio replacing $(SolutionDir) with *Undefined*

Question

I believe the problem is documented here moved here and looks like it might be a bug in visual studio, but I'm wondering if anyone knows of a workaround.

Basically I have the following two lines (among other things) one right after the other in the prebuild event.

"C:WINDOWSMicrosoft.NETFrameworkv3.5MSBuild.exe" /p:configuration=Release;platform=x86 /t:rebuild "$(SolutionDir)Folder1Project1.csproj"

"C:WINDOWSMicrosoft.NETFrameworkv3.5MSBuild.exe" /p:configuration=Release;platform=x86 /t:rebuild "$(SolutionDir)Folder2Folder3Project2.csproj" 

The first one succeeds and the other fails saying that The command ""C:WINDOWSMicrosoft.NETFrameworkv3.5MSBuild.exe" /p:configuration=Release;platform=x86 /t:rebuild "*Undefined*Folder2Folder3Project2.csproj"" exited with code 1..

Edit:
Figured out the problem was that one of the other projects with the same line as it's prebuild failed, since MSBuild itself doesn't know about the macros.

Answer 1

I fixed this by replacing all $(SolutionDir) with $(ProjectDir)...

It was due to MSBuild running each project independently, and thus not the solution. It worked fine in VS2010, but not on the build server.
