Good news! Now time for all the library and framework authors to add support for .NET Core. I know a lot of people were waiting for RTM before starting this, considering the massive changes between RC1 and RC2.
I've started a support matrix project at https://anclafs.com. Feel free to file an issue or send a PR on GitHub.
Thanks! I have a big list of things to add but I'll check this is on there and add it if they are planning (or have already added) support for Core. It started as things I had talked about in my recent book.
It depends on if you want to run ASP.NET Core on .NET Framework 4.6 or on .NET Core 1.0. It's not just the SDK that is new, Core console apps are pretty recent too, as previously it was mainly for web apps.
