title: XSLT3 Options for .NET Core in 2019
body: <p>Has anyone got XSLT3 transforms working in .NET Core 2.x+ in 2019?  </p>
  
  <p>Seems that the request to MS for <a href="https://developercommunity.visualstudio.com/content/idea/351285/implement-xslt-30-for-net.html" rel="nofollow noreferrer">XSLT2/3 support</a> hasn't moved forwards, and the Saxon people have other priorities, especially given the <a href="https://saxonica.plan.io/issues/2871" rel="nofollow noreferrer">IKVM closedown</a>.  </p>
  
  <p>Are there any other alternatives for in-process XSLT transformation?  At the moment, it seems my only choice is to wrap something up via an external service or some undesirable (for us) COM-style approach that would involve lots of marshalling of data, hurting performance.</p>
