Extending and Optimizing Xamarin.Forms Mobile Apps
summary
Shows a working Xamarin.Forms weather app that uses OpenWeatherMap, an AdMob ad added via a custom renderer, and a details page injected into native apps with Xamarin.Forms embedding. Recommends compiled XAML (XAMLc) (author reports up to ~5x faster inflation), switching ListView to recycle element caching strategy, and replacing nested StackLayouts with Grid or Margin to cut layout overhead. Notes ~70% shared logic is typical, .NET Standard retargeting in 2.3.5 pre-release, 160+ bug fixes, Tizen/Mac/WPF ports live, and embedding and fast renderers planned for 3.0 this fall.
