Specifies a recommended prefix to associate with an XML namespace when writing elements and attributes in a XAML file.
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.)|
The primary scenario for this attribute is to recommend prefixes for mappings, which are used for development environments and tools that produce or consume XAML.
Silverlight uses this attribute to decorate core assemblies such as System.Windows, to hint that x is the recommended prefix for the XML namespace that defines XAML itself (http://schemas.microsoft.com/winfx/2006/xaml). For Silverlight 4 SDK client libraries, the attribute is used to hint that sdk: is the prefix.
