Of course - I was actually surprised it still worked in VS2015. I don't expect it to be forwards compatible. (Hell, we're talking about tech that only runs in IE11 :) )

But one big difference is: Official support means updates in case of critical vulnerabilities and guarantees that, at least with IE11, it won't simply stop working after an update.

ASP.Net Core 1.x won't have any such guarantees after 2018.

And that's kinda hefty when the ASP.NET Core website (https://docs.microsoft.com/en-us/aspnet/core/) still refers to this page for guidelines as to which .NET Runtime to choose for ASP.Net Core(!) projects:
