Remarks

For XAML usage information, see x:Type Markup Extension.

Note

The {x:Type} functionality is generally for user code invocation from markup. For code that is implementing XAML support, type resolution services come from IXamlTypeResolver and are related to the implementation of the acting XAML schema context. Do not attempt to reference ProvideValue as a substitute for a IXamlTypeResolver service provider; the context you pass in might not be valid for a type resolution, and attempts to call without valid services will fail.

WPF Usage Notes

Type references are commonly used for style, template, and databinding feature areas in WPF, when these features are referenced by XAML.
