Really interesting sample on how to host Core CLR from native process: fancy Development – Hosting .NET Core Clr in your own process.
We can dream about a Webkit/Core CLR or Spartan/Core CLR integration.
EDITED: A quick google search reminds me a major advance in Silverlight that occured in 2008 Program Silverlight with the CoreCLR. In WPF/E, E stands for everywhere (Windows and Mac with a Mono version for Linux). It’s not a joke. But in 7 years, we lost Xaml and UI.
