Chapter 4. APIs
There were 1,380 APIs added in the .NET Core 1.0 release to enable specific scenarios; there was no specific theme to the API additions. You can see the complete set of changes in the API between .NET Core 1.0 and .NET Core 1.1.
The .NET Core 1.0 release does not contain the new CLI tooling (Preview 3). .NET Core 1.1 uses project.json (xproj) files rather than .csproj files.
.NET Core 1.1 is compatible with .NET Standard 1.6.0.
