Property Value

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

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.

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.
