When developing iOS and Android apps with Xamarin, developers can access every native platform API using C#. These bindings not only expose the platform APIs in C#, but add powerful C# features, such as async/await, events, delegates, and more. This is a huge advantage for developers, because they never have to leave C#, whether they're writing shared business logic, user interface, or accessing native features. One key feature developers often look for when developing cross-platform apps with Xamarin is a way to access common native features from their shared code without having to write their own abstractions or find an open source plugin created by the community.
