What are the differences between these project types, and how can I fix the difference?

Question

We are in the process of migrating from VS2012 to VS2015, and I'm running into an issue with hosting one of the web projects of a different "web project" icon.

Example project types:

1 is a successfully hosted web site

2, 4, and 5 are c# class libraries

3 is a test project

6 is a website... but is clearly different than #1. I have not successfully hosted this project at a virtual directory in VS2015, where it is in VS2012. How is #1 different from #6? I see #1 has a csproj file, #6 does not. Also the "property" windows are significantly different from the project types.

1 VS2012

1 VS2015

6 VS2012

6 2015

As you can see the property pages of the two VSes and two different project types differ pretty significantly.

My #6 project in VS2012 is hosted at http://localhost:9999/VirtualDirectory/ so its services can be accessed as (example):

http://localhost:9999/VirtualDirectory/Service1.svc

However in VS2015, I can't get it hosted under http://localhost:9999/VirtualDirectory/Service1.svc but rather only http://localhost:9999/Service1.svc I've tried changing the radio button from "use default server" to "use custom server" and specifying the base URL, however the services do not resolve when attempting to host in this manner.

What is the difference between #1 and #6 project type? What are my options for fixing my hosting differences between VS2012 and VS2015?

Right now I can change my end point connections in my web config to rather than point to http://localhost:9999/VirtualDirectory/Service1.svc instead point to http://localhost:9999/Service1.svc , but this breaks the endpoints for VS2012. Ideally I'd like to have the project configured in such a way that it works seamlessly and without config changes between running the solution in VS2012 and VS2015.

我相信1是一个Web应用程序，而6是一个网站。
