Specifies a mapping in an assembly between an XML namespace identifier and a CLR namespace within that assembly.
Assembly: System.Windows (in System.Windows.dll)
Thetype exposes the following members.
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from Attribute.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|Match||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
App assemblies are delay-loaded to improve start time. Consequently, this class is not supported in Windows Phone OS 7.1 or in Windows Phone 8.
In a XAML file, if the xmlns attribute for an element tag or attribute matches the XmlNamespace in the , a XAML processor can use the ClrNamespace and AssemblyName stored in the to check whether the element or attribute matches any type inside the namespace in the assembly. This is how a XAML processor can discover the assemblies that define the types that are created when it processes XAML into an object tree. In particular, a XAML processor uses from known and loaded reference assemblies when the namespace identifier is a URI, and the namespace is not defined by an explicit CLR-namespace/assembly combination.
