Building XML Response in ASP.NET MVC 6

I have a need to Build up and xml string and return it through an api action on one of my MVC 6 controllers. I have learned to build up an xml document using Linq-to-xml (XDocument) api. However in mvc Linq-to-xml Doesn't seem to be available as it doesnt build on the dnx core 5.0. Is there another way to build up an xml document which is works with the new Technology?

EDIT: I have an MVC 6 project and a Class Library. I am trying to use Linq-to-Xml in the class library. I need to return xml for a request that Freeswitch will make. I has a xml file format that changes slightly so i need to be able to construct the xml as needed.

The Easiest way that i have seen so far is to construct a file with Linq-to-Xml. I was thinking i could convert that to a string and return in as xml for an ajax request. If there is a better way im all ears.

MVC 6 project.json:

{
   "userSecretsId": "aspnet5-Freeswitch-8e336a2b-a401-4eec-979e-1da4917e7d74",

  "authors": [ "Londre Blocker" ],
  "tags": [ "" ],
  "projectUrl": "",

      }
    }
  },
  "dependencies": {
    "System.Xml.XDocument": "4.0.11-rc2-23623"
  }
}

Linq to Xml is availabe. You need to add a reference to "System.Xml.XDocument": "4.0.11-*" to your project.json and use the System.Xml.Linq namespace. This small tool uses Linq to Xml and is only Core Clr.

(As a side note - if you just need to write Xml using just XmlWriter will be more performant.)
