XamlMember Constructor (String, XamlType, Boolean)
Assembly: System.Xaml (in System.Xaml.dll)
For a load path that involves XamlObjectWriter, such a member cannot be written into an object graph. Using the .NET Framework XAML Services implementation, the XamlObjectWriter.WriteStartMember call throws a XamlObjectWriterException when the relevant XamlMember reports true for IsUnknown.
You should not construct a XamlMember with IsUnknown true unless your implementation can handle the exceptions from XamlObjectWriter, or you have other ways to adjust the XamlObjectWriter behavior. For example, one or more of the following might be true of your implementation:
The XAML schema context is available later.
You use a member invoker pattern.
You deliberately override XamlObjectWriter.WriteStartMember in a custom XAML writer.
