Enter Xamarin. Xamarin apps run with native performance, can use 100% of each platform's APIs, and provide significant code sharing across platforms. Xamarin apps are written in C# or F#, and benefit from the enormous .NET developer ecosystem. Xamarin development can be done on both Mac and Windows.
This talk will be an overview of Xamarin's various components followed by a deeper dive in to Xamarin.Forms. With Xamarin.Forms, you can write cross-platform user interfaces using XAML.
If you optionally want a free T-shirt, bring your laptop with Xamarin already installed. Download it from http://xamarin.com. Mac users should also come with Xcode already installed. Download it from the Mac App Store. Mac users can use the iOS Simulator which comes with Xcode. Windows users will have to either bring an Android phone with a USB cable, or install an Android emulator. Download the Xamarin Android Player, or use the VS2015 Emulator for Android. All of these downloads are large, so do them at home before SVCC starts.
