Property Value

The value of this property cannot be null (Nothing in Visual Basic).

The application URI is a critical element in OPC UA security, serving as a unique identifier for the application in security certificates and when establishing secure connections.

A generic string is used instead of System.Uri, because in some cases, the value may not represent a real URI.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
