So essentially I want to create a .wcx file, but can't follow this tutorial because I don't have my server joined to a domain (very simple setup), and therefore I cannot install the RD Connection Manager to create the .wcx.
Can someone share the contents of their .wcx file? I assume it's not much more than the URL like this: https://server1.contoso.com/RDWeb/Feed/webfeed.aspx
