Currently v5.2 is in the works, which will be released next month as beta, and after that we'll be working on .net core support for our runtime. We initially planned to ship .net core support for 5.2 but as MS postponed .netstandard2.0 till fall 2017 we did too. We hope to have .net core support for .NET standard 2.0 preview (which will come this summer) at that time.
