You are very welcome. To your goal of allowing devs to set up a RESTful API quickly without configuring controller route, .net core already provides the web api which allows you to hook up with Entity Framework really quickly. IMHO, that paradigm is a very good balance between "quick startup" and "flexible enough for further development". I suggest you to take this approach and try it out, as comparison to your codebase. Hope this help a bit. :)
