What's the right way to make a Xamarin app? While at NDC in London, Carl and Richard sat down with Gill Cleeren to talk about using the MVVM pattern as part of an overall mobile development stack. As Gill describes, MVVM brings consistency to the plumbing of the mobile app so that you can focus on the important (hard) stuff, getting the UI right, and trying to get as much common code as possible. In the end, the views end up being more device/OS specific, while the model and view-model can be shared. The tooling is complicated, but it is possible to get going fast with mobile development!
