Examples
The following code example adds a LocalizationExtenderProvider to a component.
// Adds a LocalizationExtenderProvider that provides localization support properties to the specified component.
extender = gcnew LocalizationExtenderProvider( this->component->Site,this->component );
// Adds a LocalizationExtenderProvider that provides localization support properties to the specified component.
extender = new LocalizationExtenderProvider(this.component.Site, this.component);
' Adds a LocalizationExtenderProvider that provides localization support properties to the specified component.
extender = New LocalizationExtenderProvider(Me.component_.Site, Me.component_)
The following code example includes an example component and designer. The designer uses a LocalizationExtenderProvider to add localization support properties for the component.

Remarks
LocalizationExtenderProvider can extend an IRootDesigner with a set of properties and methods that provide support for the .NET Framework localization architecture. For more about using resources, see Localization.
The localization support architecture enables designers to initialize component properties using resource files that can be swapped at run time to support a variety of languages, culture-specific styles and dynamically configurable features. You can use the methods of this class to enable designers and code generating serializers to load from resources and build initialization code that uses localization features.
The default serializers that ship with Visual Studio are already capable of localizing components and controls, but they only do so if they locate support for the .NET Framework localization architecture. To detect the presence of localization support, the serialization system must locate a public Boolean property named "Localizable" on the root designer component. If a serializer finds this property, it searches for a property of type CultureInfo named "Language" to determine the current resource configuration. Default serializers use these properties to determine if it should localize any localizable resources of the component, and if so, what CultureInfo format the resource information should be saved in.
Constructors
| LocalizationExtenderProvider(ISite, IComponent) |
Initializes a new instance of the LocalizationExtenderProvider class using the specified service provider and base component. |
Methods
| CanExtend(Object) |
Indicates whether this object can provide its extender properties to the specified object. |
| Dispose() |
Disposes of the resources (other than memory) used by the LocalizationExtenderProvider. |
| Dispose(Boolean) |
Releases the unmanaged resources used by the LocalizationExtenderProvider and optionally releases the managed resources. |
| Equals(Object) |

| SetLocalizable(Object, Boolean) |
Sets a value indicating whether the specified object supports localized resources. |
| ShouldSerializeLanguage(Object) |
Gets a value indicating whether the specified object must have its localizable values persisted in a resource. |
| ToString() |
Returns a string that represents the current object. (Inherited from Object) |
