Azure Durable Functions provides a rich set of Error Handling APIs. This post shows how Activities or Sub-Orchestrations can be re-run with the different retry options.

Activities in a workflow can call an API or run a code flow which might fail due to connection problems, network timeouts or other similar problems. If it was run a second time, it might succeed, and the flow could then complete successfully. For this, a retry Error Handling can be implemented. The HttpClient in .NET Core can implement this by using Polly. Azure Durable functions supports this directly without requiring extra Nuget packages. This can also be used to retry whole sub-orchestrations and not just single Http API calls.
