Cross Platform Mobile Development with C#

Xamarin Platform

• One language & framework

• Create native apps

• IDEs: Visual Studio or Xamarin Studio

C#

Why Xamarin?• Full control

• Familiar development environment

• Native controls

• Native performance

• Code reuse

• Active component store

Why not Xamarin?

• You need a licence

• It’s not a shared UI Platform

• You need to understand each platforms UI controls and UX paradigms

• You need a Mac for iOS dev

Xamarin Community

• 500,000 Developers worldwide

• forums.xamarin.com

• stackoverflow.com

Demo: Q&A

Two IDEs

• Visual Studio 2012/13 support with business licence

• Xamarin Studio is great too!

• Development and build can be separated

PCL vs Linked Files• PCL support (Profile158) is stable-ish

• Try PCL until you can’t.

• Plugins are easy to write

• Existing codebase may not build under PCL (e.g. XmlDocument or DataTable)
