Cannot create Container Instance using External Udp Port

See original GitHub issue

I’m running the following code to create a container instance with an external Udp port.

IContainerGroup containerGroup = await azure.ContainerGroups.Define(aciName)
               .WithRegion(region)
               .WithNewResourceGroup("myrg")
               .WithLinux()
               .WithPrivateImageRegistry("myserver", "myuser", "mypassword")
               .WithoutVolume()
               .DefineContainerInstance(aciName)
                   .WithImage("myImage")
                   .WithExternalUdpPort(4900)
                   .WithCpuCoreCount(1)
                   .WithMemorySizeInGB(1.5)
                   .Attach()
               .CreateAsync(CancellationToken.None)

I’m getting the following exception:

Following ports ‘4900’ in the ‘ipAddress’ are not used by any container in container group ‘acis11amplef3033472’.

Please note that if change the code to use WithExternalTcpPort it creates the container group and instance as expected.
