How is project type detected?

I'm trying Project Rider EAP, but given it's based on ReSharper it might belong here. Problem is as follows:

• If I create a project using ASP.NET template, the Run Configuration correctly targets XSP4 (mono ASP server), with a PROJECT_KIND (variable inside .idea/workspace.xml) of "Web".
• If I create a project using Empty template, the Run Configuration targets a .NET executable, even if I add ASP-specific Web.config, Global.asax, or others. Also, the project is not listed.

Question is: How can I make Rider detect the project as "Web", or better, which is the criteria involved when detecting project type or kind?
