1. I check in on .NET Core and ASP.NET Core every few months, to see if the tooling and documentation have stabilized. I just happened to check in yesterday, trying to create a "Hello World" ASP.NET Core web app. The skeleton project created by the "dotnet new" command doesn't match the "Getting Started" documentation on the ASP.NET Core website. After tinkering in frustration for an hour, I gave up. See you again in another few months.

2. What .NET open source community? I'm not aware of single significant open-source community project in that ecosystem that isn't a lagging imitation of something from the Java community (e.g. Akka.NET, MassTransit, etc). There's a lot of excitement around VS Code, and the possibilities of future stuff on .NET Core, but chatter on HN and Reddit isn't the same as actual shipped code.

3. If by "ecosystem" you mean web forums filled with college students chatting about it, then fine. But I think for most people, "ecosystem" refers to the availability of production-grade libraries and infrastructure components. Try naming one server-side niche in which Maven Centrals lags behind any other language in existence.

> Java has such a horrendous ecosystem, it's really unacceptable.

This has not been my experience at all. Java's ecosystem and vast libraries of battle tested software is unmatched on any platform.

You need to explain what you mean by "ecosystem".
