  10. 10. Roslyn & Xamarin • Keep track of Roslyn...‘works’ now tho’ :-) • Incorporate C# 6.0 features into Mono • “The second one is that our compiler powers our Interactive C# Shell and we are about to launch something very interesting with it. This functionality is not currently available on the open sourced Roslyn stack.” • “Roslyn really shines for IDEs” so we’ll look at how to use it in Xamarin Studio / NRefactory

  12. 12. Shared Projects • File Linking /VS 2012 Project Linker extension “on steroids” • Viable alternative to Portable Class Libraries for some uses • PCLs still great for component builders (esp with NuGet) • Shared Projects might be better for app builders • Coming toVisual Studio (download preview now) and Xamarin Studio (soon)
  13. 13. Portable Class Libraries • “PCL assembly” is generated, shared • limited framework code (predetermined by PCL profile) • Dependency Injection for platform-specific features • #if compiler directives not allowed
  14. 14. Shared Projects • no separate “output assembly”, C# is compiled into the referencing apps • use any framework code available on your target platforms • use #if compiler directives
