MSbuild task fails because “Any CPU” solution is built out of order

Question

I have two solutions to build in Teambuild, one is the application itself, the other one is the WiX installer. I want to build the application using \"Any CPU\" build config

Answer 1

Project Build Order may be set for projects belonging to the same solution. In this case, for unrelated reasons the projects need to belong to 2 different solutions.

I've discovered here that a C# project in a "Mixed Platforms" solution will build as "Any CPU", so the solution is to always use "Mixed Platforms" in the Teambuild project file.
