Authentication using Xamarin.Auth

Xamarin.Auth is a component you can use when developing Xamarin clients that authenticate with common OAuth proviers like Twitter, Facebook, etc. This component can also be used with ServiceStack OAuth providers by creating a wrapper for the WebAuthenticator.

var ssAuth = new ServiceStackAuthenticator(
    MainActivity.BaseUrl,
    "twitter", jsonServiceClient =>
    {
        var userDetails = jsonServiceClient.Get(new GetUserDetails());
        return new Account(userDetails.UserName, jsonServiceClient.CookieContainer);
    });
