I am searching for a library like Xamarin.Auth which is supporting not only android and iOS. I need support for all platforms like OsX, iOS, android and Windows Dekstop apps.
Is there something on the market?
This library is not complete but it is super super easy to extend. You basically just need to write the webview for Windows/OSX and you will be good to go. And I do accept pull requests! https://github.com/clancey/simpleauth
