This document outlines the agenda for an event introducing Xamarin and Couchbase. It will begin with social time, pizza, and introductions. James Montemagno will then give two presentations from 6:30-8:00pm introducing Xamarin, a tool for building native iOS, Android, Mac and Windows apps using C#, and Couchbase, a database. There will be a break from 8:00-8:15pm before a workshop from 8:15-9:30pm. The next mobile developers meetup will be on Android Wear in February.
