Why does Tfs2010 build my Wix project before anything else?

Question

A similar question was asked and answered about a year ago, but was either a different issue (everything was in beta) or misdiagnosed. It\'s located here: MSbuild task fails

Answer 1

I was seeing this problem (wix 3.7 not finding the dependent project output) in my local and TFS builds (for both VS2010 and VS2012).

I finally got around it by setting the msbuild property /m:1 to only use a single build process. I set /m to allow msbuild to figure out how many processes it could use to simultaneously build with.
