Defines a namespace declaration that applies to the next object scope or member scope.
Assembly: System.Xaml (in System.Xaml.dll)
A namespace declaration can be written if the current scope is a root scope, object scope, or member scope. However, can only be called immediately before a call to one of the following: , WriteStartObject, or WriteStartMember. The consecutive case is for writing multiple namespace declarations to the same node. Eventually, either WriteStartObject or WriteStartMember must be called.
does not use a Start/End metaphor. Although a XAML namespace has members in the CLR representation sense, the members are known and do not need to be represented as a special type of XamlMember for extensibility. To access the values of a NamespaceDeclaration, you access its Namespace and Prefix properties.
A namespace declaration may have a String.Empty value for the prefix. A String.Empty prefix represents a declaration of the default XAML namespace. Do not attempt to use null to represent the default prefix; it throws an exception in this API. For more information, see NamespaceDeclaration.
