Caution
IReceiveMarkupExtension has been deprecated. This interface is no longer in use.
Provides a mechanism whereby types can declare that they can receive an expression (or another class) from a markup extension, where the output is a different property type than the target property. Do not use for .NET Framework 4 implementations.

Remarks
In .NET Framework 3.0, IReceiveMarkupExtension was a WPF-specific technique for permitting types to enter a different codepath whenever any of its XAML-accessible members where set as markup extensions during XAML parsing. In .NET Framework 4, this interface is obsolete, and is replaced with a .NET Framework XAML Services implementation for how markup extensions can receive services or types can invoke markup-extension specific setter logic.
For .NET Framework 4 implementations, if types want to perform special processing when setting properties by markup extension rather than by other means, types should be defined with XamlSetMarkupExtensionAttribute attributes applied. The attribute specifies a callback, which is typically defined as a private member of the type.
In infrastructure implementations of WPF classes, most cases where XamlSetMarkupExtensionAttribute is applied reference a ReceiveMarkupExtension method that previously implemented this interface, but now instead use context through the callback.
