Command="{Binding SomeCommand}"
It will use your current controls DataContext which should hold a command property "SomeCommand"
E.G.
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ContextMenu x:Key="SomeContextMenu">
<MenuItem Header="Test Item" Command="{Binding TestCommand}" />
</ContextMenu>
</ResourceDictionary>
And in my ViewModel I would have the following property
public ICommand TestCommand { get; set; }
And in my View.xaml
<Button ContextMenu="{StaticResource SomeContextMenu}">Test Button</Button>
Therefore the buttons DataContext is my ViewModel, therefore the SomeContextMenu which is in a ResourceDictionary in a external file binds to the same DataContext as the button, and therefore finds the SomeCommand within the ViewModel.
