In order to write an equivalent tutorial for Xamarin, I am first following the UWP tutorial. Fixed many little spelling mistakes and rephrased some sentences. Fixed a crash when video is requested but the device has no camera. Fixed a crash when opening an audio recording. (Linphone.Content.FilePath returns a path with mixed '/' and '\'. I don't know why and I'm not sure I understand why the file was auto-downloaded either)
