Infrastructure should support using pre-shared key (PSK) on those devices that cannot handle full asymmetric cryptography. Leverage Microsoft Entra ID, Oauth.</li><li>**C#:** When creating a DeviceClient instance, by default, the Create method creates a DeviceClient instance that uses the AMQP protocol to communicate with IoT Hub. To use the HTTPS protocol, use the override of the Create method that enables you to specify the protocol. If you use the HTTPS protocol, you should also add the `Microsoft.AspNet.WebApi.Client` NuGet package to your project to include the `System.Net.Http.Formatting` namespace.</li></ul>|
