XmlnsDefinitionAttribute.AssemblyName Property
Silverlight
Gets or sets the name of the assembly that contains the ClrNamespace.
Namespace: System.Windows.Markup
Assembly: System.Windows (in System.Windows.dll)
Specifying the AssemblyName is optional for an application of XmlnsDefinitionAttribute, which is why an value is not part of the XmlnsDefinitionAttribute constructor signature. If AssemblyName is not set in the attribute, the assembly that this attribute is applied to will be used to return the assembly value.
