Timer Trigger with Azure Functions V3 (.NET 5)

Question

I am using .NET 5 and developing Azure Functions. When adding a new Timer Trigger function through Visual Studio it adds a file with this content:

public static class Function1
    {
        [FunctionName("Function1")]
        public static void Run([TimerTrigger("0 */5 * * * *")]TimerInfo myTimer, ILogger log)
        {
            log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
        }
    }

I'm including it as a photo here to highlight that it doesn't compile because the TimerTrigger class doesn't exist.

Intellisense suggests that I add the following using:

using Microsoft.Azure.WebJobs;

But that doesn't make sense, because that belongs to the previous version of Azure Functions. And sure enough, Intellisense detects this and show this error.

So how do I use TimerTrigger in .NET 5?

Maybe because this is relatively new, there seems to be no documentation or popular posts about this yet.

Answer 1

Try the Microsoft.Azure.Functions.Worker.Extensions.Timer package, as documented here:

Because functions that run in a .NET isolated process use different binding types, they require a unique set of binding extension packages.

You'll find these extension packages under Microsoft.Azure.Functions.Worker.Extensions.
