Binding TabControl ItemsSource to Collection of ViewModels

Question

For some reason I am having a heck of a time getting my TabControl to display properly when binding the ItemsSource to a ObservableCollection

Answer 1

I ended up using a ContentControl with a TabControl data template (like the original tutorial project). Here is the xaml code I ended up with. I did not change the code-behind from the original sample project to make this work. The ContentControl is in my MainWindow.xaml and the other two pieces of code were in a ResourceDictionary.
