__Scenario__:
User is trying to use UriPathExtensionMappings along with attribute routing. User would like to see the the appropriate information on the HelpPage(which uses ApiExplorer behind the scenes).
__Issue__:
For the following controller and actions, ApiExplorer does not return any descriptions.
```
[RoutePrefix("api/values")]
public class ValuesController : ApiController
{
[HttpGet("")]
[HttpGet("~/api/values.{ext}")]
public IEnumerable<string> GetAll()
{
return new string[] { Configuration.Services.GetApiExplorer().ApiDescriptions.Count.ToString() };
}
}
```
__Attached__ a standalone katana selfhost repro.
__Expected__: count should be 2
__Actual__: count is 0
