Azure IOT Hub - Configure your devices from a back-end service Tutorial C# Example MISSING

Hello @OJB1 ,

There are many C# IoT samples at the Code Sample page.

What you have to do is just adding a handler method for incoming desired properties:

deviceClient.SetDesiredPropertyUpdateCallbackAsync(OnDesiredPropertyChanged, deviceClient).ConfigureAwait(false);

That handler picks up changes:

private static async Task OnDesiredPropertyChanged(TwinCollection desiredProperties, object userContext)
{
    Console.WriteLine("One or more device twin desired properties changed:");
    Console.WriteLine(JsonConvert.SerializeObject(desiredProperties));
    var client = userContext as DeviceClient;
    var reportedProperties = new TwinCollection
    {
        ["DateTimeLastDesiredPropertyChangeReceived"] = DateTime.Now
    };
    await client.UpdateReportedPropertiesAsync(reportedProperties).ConfigureAwait(false);
    Console.WriteLine("Sent current time as reported property to device twin");
}
