Trying to access the current URL as below succeeds in IIS host:

var uri = this.Url.Route(null, new { id = value.Id });

but throws 'ArgumentNullException' exception with self-host. The error message is: 'Value cannot be null. Parameter name: name' and stack trace:

Everything else seems to work otherwise and all routes are correctly set-up. Is this a bug? Any ideas?
