Native User Interfaces
Apps built using Xamarin contain standard, native user interface controls. Apps not only look the way the end user expects, but they behave that way too.
Native API Access
Apps built using Xamarin have access to the full spectrum of functionality exposed by the underlying platform and device, including platform-specific capabilities like ARKit and Android Multi-Window mode.
Apps built using Xamarin leverage platform-specific hardware acceleration, and are compiled for native performance. This can’t be achieved with solutions that interpret code at runtime.
