Definition

protected:
 virtual bool LookupIsUnknown();
protected virtual bool LookupIsUnknown ();
abstract member LookupIsUnknown : unit -> bool
override this.LookupIsUnknown : unit -> bool
Protected Overridable Function LookupIsUnknown () As Boolean

Returns

Boolean

true if this XamlType represents a nonresolvable type; otherwise, false.

Remarks

This method can be invoked by calls to IsUnknown.

The default implementation can use CLR reflection. For a null UnderlyingType, it returns true.

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