title: CoreCLR and project Mono relationship after Microsoft open-sourced the .NET
body: <p>Could someone explain to me what is the current relationship between Mono and the open source/Linux portable .NET stack (CoreCLR, CoreFX, Roslyn, ASP.NET) recently made available by Microsoft?  </p>
  
  <p>It's rather clear these projects overlap so I'm curious what's the roadmap for both of them - will Mono somehow replace their own component with the new ones from Microsoft, or are they going to coexist somehow? </p>
