Resolve command in WPF. what is the resolve word?

Question

Can someone explain this XAML statement, particularly what is the Resolve?

<MenuItem Header="_Load File" Command="{Resolve {Type Commands:LoadFile}}" />

This snippet was taken from NHprof.exe MainMenu.xaml file, using reflector.

Answer 1

Since it is in {}, this is a MarkupExtension. In this case it is a custom extension called ResolveExtension (by convention, the Extension suffix is not needed). So look in the code for the class ResolveExtension.
