This project has been deprecated and archived, with the C# implementation of buttplug having moving to an FFI layer on top of buttplug-rs. This new FFI layer has not been tested with Xamarin, meaning this repo will not see updated based on new versions of the library.
If we get to a point where Xamarin works with buttplug-rs FFI, implementations and examples will be hosted in the buttplug-rs-ffi repo:
https://github.com/buttplugio/buttplug-rs-ffi/
Examples of using Buttplug C# with the Xamarin Bluetooth Manager to make C# mobile apps for Android and iOS.
