XmlnsCompatibleWithAttribute Class


Specifies that a XAML namespace can be subsumed by another XAML namespace. Typically, the subsuming XAML namespace is indicated in a previously defined XmlnsDefinitionAttribute.

public ref class XmlnsCompatibleWithAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Assembly, AllowMultiple=true)]
public sealed class XmlnsCompatibleWithAttribute : Attribute
type XmlnsCompatibleWithAttribute = class
    inherit Attribute
Public NotInheritable Class XmlnsCompatibleWithAttribute
Inherits Attribute


Applying the XmlnsCompatibleWithAttribute enables an assembly to provide a new and compatible namespace for another XAML namespace, as previously indicated by XmlnsDefinitionAttribute. For example, "http://www.adatum.com/2003/controls" could be marked compatible with a defined XAML namespace identified as "http://www.adatum.com/2005/controls" through the following assembly-level attributes:

[assembly:System.Windows.Markup.XmlnsDefinition("http://www.adatum.com/2005/controls", "Adatum.Controls")]  
[assembly: System.Windows.Markup.XmlnsCompatibleWith("http://www.adatum.com/2003/controls", "http://www.adatum.com/2005/controls")]  

In previous versions of the .NET Framework, this class existed in the WPF-specific assembly WindowsBase. In .NET Framework 4, XmlnsCompatibleWithAttribute is in the System.Xaml assembly. For more information, see Types Migrated from WPF to System.Xaml.


XmlnsCompatibleWithAttribute(String, String)
