Async programming and Azure functions

Question

In the Azure functions \"Performance considerations\" part, Functions Best Practices, under \"Use async code but avoid blocking calls\", async programming is the su

Answer 1

You can make the function async:

public static async Task Run(
    [ServiceBusTrigger("topicname", "subname", AccessRights.Manage, Connection = "TopicConnection")]string message,
    TraceWriter log)
{
    try
    {
        log.Info($"C# ServiceBus topic trigger function processed message: {message}");
        await PushToDb(message, log);
    }
    catch(Exception ex)
    {
        log.Info($"Exception found {ex.Message}");
    }
}

The Functions runtime allows you to make your function async and return a Task.

In this case we can just await the call so we can handle exceptions normally.
