The work so far has been on master, and a lot of it is actually in the latest release of the SDK. For example, the new configuration system (using Microsoft.Extensions.Configuration to read JSON or other formats) is actually supported in the latest SDK. You just have to use it within .Net 4.5, it can’t run in .Net Core yet.
My hope is that we won’t need a feature branch, and we’ll be able to dual compile the SDK and include both versions in the Nuget. So far that plan seems to be holding, but we’ll see how well it works when we get down to it.
