How do I make an XML file an embedded resource in a vNext (ASP.NET 5) class library?

I have an MVC 6 (vNext/ASP.NET 5) project, with one class library for the DAL(Data Access Layer). Now I am getting an exception because NHibernate can’t find the mapping file for an entity I am trying to persist. I have seen strict instructions to mark this XML mapping file as an embedded resource and not to copy to output, but in none of the three property pages I manage to open for this file, is there anywhere to stipulate this.

Multiple Calls to the same Web Service Blocking?

We have a page that makes a request to a 3’rd party web service. When under heavy load this response time extends significantly, however the 3’rd party reports back that there times for processing remains constant. There timings show that from the time they receive a request to the time they send it back is always around 1.5-2.0 seconds. Now we are experiencing wait times of over 20 seconds. My understanding of ASP.NET is that each request will run on a IIS thread pool thread and make the request to the 3’rd party service return and process. So I don’t really understand what could be blocking on our end. Is there something I am missing?? Is there a threshold limit beyond IIS that is blocking?
