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.

Namespace:   System.Windows.Markup
Assembly:  System.Xaml (in System.Xaml.dll)


[AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple = true)]
public sealed class XmlnsCompatibleWithAttribute : Attribute

System_CAPS_pubmethodXmlnsCompatibleWithAttribute(String, String)

Initializes a new instance of the XmlnsCompatibleWithAttribute class.


Gets the subsuming namespace identifier reported by this attribute.


Gets the reference namespace identifier reported by this attribute.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from 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.
