Use the add method wizard to add a method to an interface in your project. If the project contains a class associated with the interface, the wizard also adds the method to the class.

-
From the Visual Studio main menu, choose View > Class view. In the Class View pane, expand the project node to display the interface you want to add the method to.
[!NOTE] You can also add methods to dispinterfaces. Unless the project is attributed, dispinterfaces are located under the library node.
-
Right-click the name of the interface.
-
On the shortcut menu, choose Add > Add Method.

In the Add Method wizard dialog box, provide the information to create the method as described in the next section.
