Azure Event Grid System Events client library for .NET - version 1.0.0-beta.1
Azure Event Grid allows you to build applications with event-based architectures. The Event Grid service fully manages all routing of events from any source to any destination, for any application. Azure service events and custom events can be published directly to the service, where the events can then be filtered and sent to various recipients, such as built-in handlers or custom webhooks. To learn more about Azure Event Grid: What is Event Grid?
Use the client library for Azure Event Grid System Events to:
Deserialize Event Grid system events into strongly typed models.

Install the client library for .NET with NuGet:
dotnet add package Azure.Messaging.EventGrid.SystemEvents --prerelease
You must have an Azure subscription and an Azure resource group with a custom Event Grid topic or domain. Follow this step-by-step tutorial to register the Event Grid resource provider and create Event Grid topics using the Azure portal. There is a similar tutorial using Azure CLI.
In order for the client library to interact with a topic or domain, you will need the endpoint
of the Event Grid topic and a credential
, which can be created using the topic's access key.
You can find the endpoint for your Event Grid topic either in the Azure Portal or by using the Azure CLI snippet below.
az eventgrid topic show --name <your-resource-name> --resource-group <your-resource-group-name> --query "endpoint"
The access key can also be found through the portal, or by using the Azure CLI snippet below:
az eventgrid topic key list --name <your-resource-name> --resource-group <your-resource-group-name> --query "key1"
Once you have your access key and topic endpoint, you can create the publisher client as follows:
// Construct the client using an Endpoint for a namespace as well as the shared access key
var senderClient = new EventGridSenderClient(new Uri(namespaceTopicHost), topicName, new AzureKeyCredential(namespaceKey));
Azure Event Grid provides integration with Entra ID for identity-based authentication of requests. With Entra ID, you can use role-based access control (RBAC) to grant access to your Azure Event Grid resources to users, groups, or applications. The Azure Identity library provides easy Azure Active Directory support for authentication.
To send events to a topic or domain using Azure Active Directory, the authenticated identity should have the "EventGrid Data Sender" role assigned.
// Construct the sender client using an Endpoint for a namespace as well as the DefaultAzureCredential
var senderClient = new EventGridSenderClient(new Uri(namespaceTopicHost), topicName, new DefaultAzureCredential());
We guarantee that all client instance methods are thread-safe and independent of each other (guideline). This ensures that the recommendation of reusing client instances is always safe, even across threads.

You can familiarize yourself with different APIs using Samples.
Describe common errors and exceptions, how to "unpack" them if necessary, and include guidance for graceful handling and recovery.
Provide information to help developers avoid throttling or other service-enforced errors they might encounter. For example, provide guidance and examples for using retry or connection policies in the API.
If the package or a related package supports it, include tips for logging or enabling instrumentation to help them debug their code.
