Property Value

This value of this property can be null (Nothing in Visual Basic).

The default value of this property is null.

Because OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement has an implicit conversion to OpcLabs.EasyOpc.UA.UAEndpointDescriptor, you can simply use the returned OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement in any place where OpcLabs.EasyOpc.UA.UAEndpointDescriptor is expected as input, and the corresponding endpoint descriptor will be constructed automatically from the application element. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement.ToUAEndpointDescriptor static method instead.
