Ensure GitInfo is updated every build

[xz891964]

I've got a solution with 2 projects (.csproj), call them A and B. Project A references GitInfo. When I make a change only in project B, project A isn't built because it's unchanged, and therefore ThisAssembly.Git doesn't get updated. I'd like to ensure ThisAssembly.Git gets updated every build, regardless of whether the referencing project was modified. I imagine this is a very common scenario, how do others deal with it?
