Support web.config transformations on build
It appears that WebAPI projects do not automatically transform web.config files on build. After getting used to this for other .NET project types, it's difficult to make the exception in the case of WebAPI projects.
Web API projects are no different than any other web application project, so web-config transformations should just work.
This should just work for the Web API project template. Could you walk us through what you tried and what didn't work?
