15. .NET Core Available now: .NET Core 1.0 Full supported RTM runtime Includes .NET Core SDK and tools Preview 2 Coming next .NET Core 1.1: ASP.NET Core, .NET Core Runtime and Entity Framework updates ASP.NET: URL Rewriting, Response Caching, View Precompilation, Azure integration EF Core: Connection Retries, SQL In Memory Tables . NET Core Tooling RTM: Unified tools for all .NET Platforms based on enhanced MSBuild

16. Continuous innovation Current Long Term Support (LTS) • Use the current release to get the latest features • Supported as long as you keep updating to the latest • Use the Long Term Support release as the most stable platform • LTS is fully supported for 3 years and receives regular important updates • You can mix and match your strategy (even in the same machine!)

21. .NET Standard Library One library to rule them all Learn one API Reuse your code across .NET platforms Easily consume third party / OSS libraries .NET Standard 1.x Russian doll model (1.0 – 1.6) across all existing PCL profiles and target frameworks Much simpler and straightforward model. Use them now! Two constraints: API surface relatively small, because .NET Core was small Can’t reference the vast number of libraries already available for .NET Framework

22. .NET Standard 2.0 Much bigger API surface Extended to cover intersection between .NET Framework and Xamarin .NET Core will bring the new API surface to comply with .NET Standard 2.0 .NET Framework interop Compatibility shim allows .NET Standard based libraries to reference existing .NET Framework binaries No recompile required Limited to .NET Framework libraries that only use APIs in .NET Standard (which are most of them)

23. APIs in .NET Standard 2.0 XLinq • XML Document • XPath • Schema • XSL XML BinaryFormatter • Data Contract • XML SERILIZATION Sockets • Http • Mail • WebSockets NETWORKING Files • Compression • MMF IO Threads • Thread Pool • Tasks THREADING Primitives • Collections • Reflection • Interop • Linq CORE
