问题
I'm tring to follow the Configuring tutorial of the Facebook SDK for .NET.
But when I add the RootFrame.UriMapper = new FacebookUriMapper(); line of code the NavigationService seems stop to work.
The app start's fine but the command NavigationService.Navigate(new Uri("/Views/LoginPage.xaml", UriKind.Relative)); inserted in a Button on init app page don't work. Other commands on same button like a MessageBox.Show works fine.
Thank you for any help you can provide.

The file FacebookUriMapper in the Facebook.Client SDK has a bug. When looking via debugger, it doesn't redirect to the target page, but switches back to the default RedirectUri in Facebook.xml. Clone the repository in your computer, open the WP8 solution, restore required Nuget packages. Now, open FacebookUriMapper.cs file, modify the last else block to return uri. Build and use this as your referenced assembly. NavigationService works absolutely fine after this.
