Remarks

Many APIs in the XamlType class provide information about XAML types, where the concept they report on is similar to particular sections of the XAML specification [MS-XAML].

XamlType is used extensively in the .NET Framework XAML Services API for reporting information about a XAML type. XamlType reports the information that you might need to know about a XAML type in order to work with an instance or to access its members from a XAML node stream, or a similar XAML representation. Its reporting is similar to how the Type in the CLR type system, together with reflection classes such as MemberInfo, provide information about a CLR type and its usage.

To extend the XAML type system, you can derive from XamlType. To do so effectively, you might also need to implement a XamlTypeInvoker. The XamlTypeInvoker enables the generalized XAML type system to work with the type system backing that you specify as part of the invocation behavior. The specific custom XamlTypeInvoker provides a way to reduce the dependencies on the CLR type system, which are used by the default XamlType behavior.

Constructors

XamlType(String, IList<XamlType>, XamlSchemaContext)	Initializes a new instance of the XamlType class based on a string name for the type.
XamlType(String, String, IList<XamlType>, XamlSchemaContext)	Initializes a new instance of the XamlType class based on the XAML namespace and a string name for the type. This constructor is exclusively for analysis and XAML-node recording of type usages that are known to not have backing in the supporting type system and XAML schema context.
XamlType(Type, XamlSchemaContext)	Initializes a new instance of the XamlType class based on the underlying CLR type information.
XamlType(Type, XamlSchemaContext, XamlTypeInvoker)	Initializes a new instance of the XamlType class based on underlying type information and a XamlTypeInvoker implementation.
