Go Mobile with C# and Xamarin

Roslyn & Xamarin

http://tirania.org/blog/archive/2014/Apr-09.html

• 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

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 to Visual Studio (download preview now) and Xamarin Studio (soon)

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

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
