/*
  In App.xaml:
  <Application.Resources>
      <vm:ViewModelLocator xmlns:vm="clr-namespace:MvvmLightSample"
                           x:Key="Locator" />
  </Application.Resources>
  
  In the View:
  DataContext="{Binding Source={StaticResource Locator}, Path=ViewModelName}"

  You can also use Blend to do all this with the tool's support.
