XamlType.LookupMarkupExtensionReturnType Method

.NET Framework 4.6 and 4.5

Returns a value that provides the type information for the returned ProvideValue of this XamlType, if it represents a markup extension.

Namespace:  System.Xaml
Assembly:  System.Xaml (in System.Xaml.dll)

protected virtual XamlType LookupMarkupExtensionReturnType()

Return Value

Type: System.Xaml.XamlType
A XamlType object for the return type for markup extension usage; otherwise, null, if this XamlType does not represent a markup extension.

This method can be invoked by calls to MarkupExtensionReturnType.

The default implementation returns a XamlType on the basis of reading MarkupExtensionReturnTypeAttribute. It can also check BaseType for the attribute if no attribute is found on the immediate underlying type. If a value is not available, it returns null.

Override this method if you want MarkupExtensionReturnType to use different logic.
