Not Implemented Exception thrown when using Windows phone 8.1 SDK

[thehetz]

I am working through the samples for login on the facebooksdk.net site and have the sample for login working for a Windows store app working as expected.

I cannot get the sample for a Windows Phone app to work properly, however. When I follow the sample, I have to first modify the XAML namespace sample from: xmlns:facebookControls="clr-namespace:Facebook.Client.Controls;assembly=Facebook.Client" to xmlns:facebookControls="using:Facebook.Client.Controls". This is the same as it is for the Windows Store application and prevents a compilation error in VS 2013 from occurring. Even after doing this, I do NOT see the login button appear in the designer as I do for the Windows app. At runtime the button does appear in the emulator or on a device. When clicking the Facebook login button a “Not Implemented Exception” is thrown from deep in the stack which appears to be coming from Facebook.Client.FacebookSessionClient as can be seen in this stack trace:

I am wondering if this is something that is known and if there is a work around for this issue? Here are the versions of the NuGet packages that I am currently using:
Facebook: 6.0.10.0
Facebook.Client: 0.9.1.0
Visual Studio 2013 R3 with .NET 4.5.1
