Provides a means to parse elements that permit mixtures of child elements or text.
Assembly: PresentationCore (in PresentationCore.dll)
Thetype exposes the following members.
For purposes of establishing or defining a content property or content model in WPF, is obsolete. Apply the ContentPropertyAttribute to a custom class instead.
For purposes of XAML parser/processor behavior, is obsolete. Collection behavior is now integrally part of the XAML type system and XAML processor implementations should use the dedicated APIs in the System.Xaml assembly. General user code should use the Add methods on the collection type used for the relevant type's child collection property.
Callers in .NET Framework version 4 targeted applications that attempt to use the API for one of its original .NET Framework 3.0 era purposes (WPF content model, XAML processing) should expect that many current -implementing classes will return NotImplementedException or similar results for the API.
