The library provides access to the Device Update for IoT Hub service that enables customers to publish updates for their IoT devices to the cloud, and then deploy these updates to their devices (approve updates to groups of devices managed and provisioned in IoT Hub).

Getting started

The complete Microsoft Azure SDK can be downloaded from the Microsoft Azure Downloads page and ships with support for building deployment packages, integrating with tooling, rich command line tooling, and more.

For the best development experience, developers should use the official Microsoft NuGet packages for libraries. NuGet packages are regularly updated with new functionality and hotfixes.

Prerequisites

Microsoft Azure Subscription: To call Microsoft Azure services, you need to create an Azure subscription
Device Update for IoT Hub instance
Azure IoT Hub instance

Install the package

Install the Device Update for IoT Hub client library for .NET with NuGet:

dotnet add package Azure.IoT.DeviceUpdate

Authenticate the Client

In order to interact with the Device Update for IoT Hub service, you will need to create an instance of a TokenCredential class and pass it to the constructor of your DeviceUpdateClient and DeviceManagementClient class.

Key concepts

Device Update for IoT Hub is a managed service that enables you to deploy over-the-air updates for your IoT devices. The client library has three main components:

DeviceManagementClient: device, group, deployment management (enumerate, create, retrieve, delete device, group, deployment, etc.)
DeviceUpdateClient: update management (import, enumerate, delete, etc.)

You can learn more about Device Update for IoT Hub by visiting Device Update for IoT Hub.

Examples

You can familiarize yourself with different APIs using Samples.

Troubleshooting

All Device Update for IoT Hub service operations will throw a RequestFailedException on failure with helpful ErrorCodes.

For example, if you use the GetUpdateAsync operation and the model you are looking for doesn't exist, you can catch that specific HttpStatusCode to decide the operation that follows in that case.

try
{
    Response update = await _updatesClient.GetUpdateAsync(
      "provider", "name", "1.0.0.0");
}
catch (RequestFailedException ex) when (ex.Status == (int)HttpStatusCode.NotFound)
{
    // Update does not exist.
}
