ResourceDictionary.Remove Method (String)
Removes a specific item from the ResourceDictionary.
Assembly: System.Windows (in System.Windows.dll)
The general definition of Remove is that it removes the "first occurrence" of an item. Because this is a keyed dictionary, each item is identified uniquely by key, and the concept of "first occurrence" does not apply.
See XamlName Grammar for string value restrictions on key. The value used for key must conform to this grammar.
