How can I use a single Visual Studio solution to build both x86 and x64 at the same time?

Question

I\'ve got an x86 Visual Studio solution with many project files in it. Some of the DLL files are designed to work as plug-ins to other applications on a user\'s system.

I think the best way of doing this is to invoke MSBuild from the command line. It shouldn't need editing of MSBuild files. Just run

msbuild myproj.sln /p:Configuration="Debug|Win32"
msbuild myproj.sln /p:Configuration="Debug|x64"

I assume that if a developer is using Visual Studio then they'll only be generating the DLL files so they can debug with them, and that you have a separate build process if you're actually deploying the DLL files.
