CloudNative CloudEvent support for Azure.Messaging.EventGrid library for .NET

  • Cikk

This library can be used to enable publishing CloudNative CloudEvents using the Azure Event Grid library.

Getting started

Install the package

Install the client library from NuGet:

dotnet add package Microsoft.Azure.Messaging.EventGrid.CloudNativeCloudEvents --prerelease

Prerequisites

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.

Authenticate the client

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"

Creating and Authenticating EventGridPublisherClient

Once you have your access key and topic endpoint, you can create the publisher client as follows:

EventGridPublisherClient client = new EventGridPublisherClient(
    new Uri("<endpoint>"),
    new AzureKeyCredential("<access-key>"));

Examples

EventGridPublisherClient client = new EventGridPublisherClient(
        new Uri(TestEnvironment.CloudEventTopicHost),
        new AzureKeyCredential(TestEnvironment.CloudEventTopicKey));

var cloudEvent =
    new CloudEvent
    {
        Type = "record",
        Source = new Uri("http://www.contoso.com"),
        Data = "data"
    };
await client.SendCloudNativeCloudEventAsync(cloudEvent);

Troubleshooting
