XmlnsDefinitionAttribute Class
 

Specifies a mapping on a per-assembly basis between a XAML namespace and a CLR namespace, which is then used for type resolution by a XAML object writer or XAML schema context.

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

NameDescription
System_CAPS_pubmethod XmlnsDefinitionAttribute

Initializes a new instance of the XmlnsDefinitionAttribute class.

NameDescription
System_CAPS_pubproperty

Gets or sets the name of the assembly associated with the attribute.

System_CAPS_pubproperty

Gets the string name of the CLR namespace specified in this attribute 

System_CAPS_pubproperty

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

System_CAPS_pubproperty

Gets the XAML namespace identifier specified in this attribute.

NameDescription
System_CAPS_pubmethod Equals

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.)

System_CAPS_pubmethod GetHashCode

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

System_CAPS_pubmethod GetType

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

System_CAPS_pubmethod IsDefaultAttribute

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

System_CAPS_pubmethod Match

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

System_CAPS_pubmethod ToString

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

NameDescription
System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetIDsOfNames

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfo

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeGetTypeInfoCount

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

System_CAPS_pubinterface System_CAPS_privmethod _AttributeInvoke

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

Apply one or more XmlnsDefinitionAttribute attributes to assemblies in order to identify the types within the assembly for XAML usage.

To find the appropriate types that back object element usages or object references in a XAML file, a XAML processor searches each referenced assembly for XmlnsDefinitionAttribute applications. Generally the XAML schema context supplies this information.

In a XAML file, if the xmlns attribute for an object element or property element matches the in the XmlnsDefinitionAttribute, the XAML processor uses the and stored in the XmlnsDefinitionAttribute for type resolution against types in the assembly.

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