MarkupExtension Class

Provides a base class for all XAML markup extensions.

Namespace:  System.Windows.Markup
Assembly:  WindowsBase (in WindowsBase.dll)

public ref class MarkupExtension abstract
This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.

Markup extensions return objects based on string attribute values or markup elements in XAML. Markup extensions return objects in a more sophisticated way than type converters alone can accomplish. In particular, the ProvideValue method of each extension can use an IServiceProvider at runtime that can provide context. This IServiceProvider is then queried for specific services that pass information, such as IProvideValueTarget or IXamlTypeResolver.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
