This week I've learned WPF while making a Metro application using the Win8 dev preview. I watched an excellent MVVM video but for some reason my properties in the code did not get updated when I changed the value in a textbox. Turns out in Win8 Metro databinding is one-way and not two-way like it used to be. Mad

Now all my databindings need to have:

{Binding Customer.Name, Mode=TwoWay}
