DynamicResourceExtension Class

Implements a markup extension that supports dynamic resource references made from XAML.

Namespace:  System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)

public class DynamicResourceExtension : MarkupExtension
For XAML information, see DynamicResource Markup Extension.

Dynamic resource references are necessary when referencing content that might change at run-time. The reasons for the content change might be application-initiated or might be external. One example is if you are including styles that rely on system resources that report user-configured preferences, such as themes, font settings and so on.

This class is a markup extension implementation. Markup extension classes in WPF exist mainly to provide infrastructure support for some aspect of the WPF XAML processor implementation, and the members exposed by the markup extension classes are not typically called from directly user code. This class particularly supports the DynamicResource Markup Extension usage from XAML. For more information about dynamic resource references, see DynamicResource Markup Extension.


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