.NET Core was in some ways inspired by the ALT .NET movement(I think). I'm not entirely sure where it started, but if my own experience (from 2012) is any indication then it was very much related to people coming out of enterprise and government, that had to deal with ASP.NET and WebForms, but didn't want to deal with it, because they had experience with web frameworks that weren't the nightmare ASP.NET and WebForms were. I worked with a few of those in 2012 and people were hopeful about .net core. But the major difference between .net core and typescript besides the historical mental baggage and the way Microsoft typically responds to patches to open source projects is that typescript was building on a massive JavaScript base. And because ECMAScript development was active these two were building on each other. I think C# is a lot nicer than Java but unfortunately with the community mismanagement it's not really a serious contender unless you HAVE to be in that environment(i.e. Microsoft Stack in US healthcare/govt for example)
