The ContentWrapperAttribute type exposes the following members.

Public method ContentWrapperAttributeInitializes a new instance of the ContentWrapperAttribute class.
Public property ContentWrapperGets the type that is declared as a content wrapper for the collection type associated with this attribute.
Public property TypeIdGets a unique identifier for this attribute. (Overrides AttributeTypeId.)
Public method EqualsDetermines whether the specified ContentWrapperAttribute is equivalent this ContentWrapperAttribute by comparing the ContentWrapper properties. (Overrides AttributeEquals(Object).)
Public method GetHashCodeGets a hash code for this instance. (Overrides AttributeGetHashCode.)
Public method GetTypeGets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public method MatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public method ToStringReturns a string that represents the current object. (Inherited from Object.)
Explicit Interface Implementations
Explicit interface implemetation Private method _AttributeGetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeInvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Foreign content refers to cases where the type system constraints on the type of the content property do not capture all of the possible content cases that XAML usage for the owning type would support. For example, XAML support for content of a particular type might support strings in a strongly typed generic CollectionT.

InlineCollection is an example of a WPF class that has the ContentWrapperAttribute attribute applied. In this case there are two separate attributed wrapper classes.

In previous versions of the .NET Framework, this class existed in the WPF-specific assembly WindowsBase. In .NET Framework 4, ContentWrapperAttribute is in the System.Xaml assembly. For more information, see Types Migrated from WPF to System.Xaml.
