Remarks
Apply this attribute to your VSPackage class that inherits from Package or implements IVsPackage to cause your class to be automatically loaded when a specified UI context is active.
This attribute makes your VSPackage an extender (an object which implements IExtenderProvider). The GUID passed to the constructor determines the context in which the package loads.
This attribute class is only used to provide data for external registration tools. It does not have any effect on the runtime behavior of the VSPackage.
注意
Visual C# automatically appends the word "Attribute" to the name of any attribute class. In Visual C# code, refer to this attribute as ProvideAutoLoad.
