This constructor creates an instance of the attribute that is used with a method of a Web Parts control acting as a provider. This method becomes the connection point between the provider and the consumer. Typically, the way you use this constructor is to declare a ConnectionProviderAttribute metadata element on a method that you want to designate as a callback method in a provider control.
The displayName parameter is a friendly name of the provider connection point that is used by the ConnectionsZone control to represent a provider's connection point in the UI.
The following code example demonstrates using the ConnectionProviderAttribute class, by showing how to declare the ConnectionProviderAttribute metadata element on a callback method in a provider control. Note that the simplest overload of the constructor is used; only the displayName parameter value is supplied. For the full code required to run the code example, see the ConnectionProviderAttribute class overview.
