I implemented cognito identity and sync in xamarin PCL project. it works fine in android but when I try in UWP. I am getting an exception. Does that mean it only work for android and ios using xamarin.forms?

@EmilAlipiev The Xamarin SDK has migrated to the .NET SDK https://github.com/aws/aws-sdk-net This supports more platforms, you can add functionality via NuGet of individual services. You can read about the Xamarin part of the SDK here: http://docs.aws.amazon.com/mobile/sdkforxamarin/developerguide/ and the base SDK https://aws.amazon.com/documentation/sdk-for-net/
