In Xaml I can set a custom attached property using local:TestClass.TestProperty="1"
An I can bind to a custom attached property using {Binding Path=(Namespace:[OwnerType].[PropertyName])} {Binding Path=(local:TestClass.TestProperty)}
But how do I specify the namespace when I need to use a custom attached property in a SortDescription? I can bind to an attached property using new SortDescription("(Grid.Row)", ListSortDirection.Descending) but here I can t set a namespace anywhere...
