This is referencing this question: How to login to facebook in Xamarin.Forms. I use a similar solution which uses Xamarin.Facebook.Android and Xamarin.Facebook.iOS for auth (https://github.com/mikeapple/XamarinFormsNativeFBLogin) and works perfectly, but I can't even begin to work out how to do native auth on UWP, there doesn't even seem to be Nuget to support this.
Does anyone have a workable solution to this problem that they would be prepared to share, or know of one that I could study, that would fit without having to repurpose my existing project too much?
Thanks
