Listener Hosted Control (Hosted Control)
Use the Listener Hosted Control type of hosted control, introduced in Unified Service Desk 2.0, to configure a custom listener for your auditing, diagnostic, and trace logs. The hosted control contains a reference to your assembly and class that contains the code for the custom listener. This type of hosted control doesn’t have any predefined UII actions or events.
