How to I tell my MSBuild (probably in my project file) that I want to use XDT transforms on my own XML file? I have the standard Web.config and Web.Release.config which Visual Studio shows as a dependent file of Web.config. I also have foo.config and foo.Release.config.
The Release version is not displaying as dependent on foo.config. It is just displaying as a normal content file.
More importantly, the transform doesn't happen on build. No errors - it just isn't even trying to merge the files.
I assume the two issues are related. If I get them configured correctly, the transforms will just work as expected.
If it matters, I am using VS2013.
