<AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple := True)> _
Public NotInheritable Class XmlnsDefinitionAttribute _
    Inherits Attribute

Visual Basic (Usage)

Dim instance As XmlnsDefinitionAttribute

[AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple = true)]

Visual C++

XAML

You cannot directly create an instance of this class in XAML.

Remarks

The XML namespace can be used in a XAML markup file.

To find the appropriate types for an element and attributes in a XAML file, the XAML processor searches each referenced assembly for XmlnsDefinitionAttribute objects.

In a XAML file, if the xmlns attribute for an element tag or attribute matches the XmlNamespace in the XmlnsDefinitionAttribute, the XAML processor uses the ClrNamespace and AssemblyName stored in the XmlnsDefinitionAttribute instance to check if the element or attribute matches any type inside this namespace in the assembly.

Inheritance Hierarchy

System..::.Object
System..::.Attribute
System.Windows.Markup..::.XmlnsDefinitionAttribute

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
