This attribute is used only for registration purposes and does not affect runtime behavior.
Apply this attribute to classes implementing a VSPackage that either provides Toolbox items with a non-standard clipboard format or does not support one or more the default Toolbox clipboard formats.
A VSPackage without this attribute must support all default Toolbox clipboard types.
For a list of the default Toolbox clipboard types supported by a VSPackage, see Extending the Toolbox.
Use of this attribute by itself does not register a VSPackage as a provider of items with a given clipboard. An instance of the attribute must be applied to register the VSPackage as providing objects of the specified format.
Only one clipboard format is registered as supported for each instance of this attribute applied to a class. To indicate that multiple formats are supported, multiple instances of the attribute must be applied to the class.
Note C# automatically appends the word "Attribute" to the name of any attribute class. In C# code, refer to this attribute as ProvideToolboxFormat.
