[BUG] ServiceBusRetryOptions seems to be not working

Library name and version

Azure.Messaging.ServiceBus 7.6.0

Describe the bug

We recently experienced ServiceBus issues where after receiving a bunch of ServiceTimeout exceptions noticed in application insights no retries.

We have ServiceBusRetryOptions setup as follows for our client:

var serviceBusClientOptions = new ServiceBusClientOptions()
            {
                RetryOptions = new ServiceBusRetryOptions()
                {
                    MaxRetries = 5,
                    Mode = ServiceBusRetryMode.Exponential,
                    MaxDelay = TimeSpan.FromSeconds(30),
                    TryTimeout = TimeSpan.FromSeconds(30)
                }
            };

And in application insights it is shown to only have taken 30s.

Expected behavior

Expect request duration to be longer as it should include all 5 retries.

Actual behavior

Request seems to return ServiceTimeout exception after first attempt.

Reproduction Steps

Difficult to reproduce on demand.

Environment

Azure AppService .Net Version: 6.0.1

Thank you for the additional context, @pjonusas. Unfortunately, the behavior that you’re seeing is expected in this scenario. Due to the way that transactions work with Service Bus, retries cannot be performed when there is an active ambient transaction. Looking over the docs, it seems that we did a poor job of calling this out. I’ve opened #27637 and #90071 to track getting retry guidance added.

I’m going to mark this as addressed, but please feel free to unresolve if you’d like to continue the discussion.

Hi @pjonusas, since you haven’t asked that we “/unresolve” the issue, we’ll close this out. If you believe further discussion is needed, please add a comment “/unresolve” to reopen the issue.
