Why should you care?

API must not run 10-minute ERP reconciliation synchronously; queues smooth load and survive transient OpenAI 429.

See it live — copy this example

Paste into an ASP.NET Core 8+ / AgentNest project, then run with dotnet run (set your API keys in user-secrets).

// AgentNest.Queues/AgentJobPublisher.cs
public sealed class AgentJobPublisher(ServiceBusSender sender)
{
    public Task EnqueueAsync(AgentJob job, CancellationToken ct) =>
        sender.SendMessageAsync(new ServiceBusMessage(JsonSerializer.Serialize(job))
        {
            MessageId = job.IdempotencyKey,
            Subject = job.AgentName
        }, ct);
}

What happened?

• AgentJobPublisher sends serialized jobs with idempotency MessageId so duplicate CRM webhooks do not double-enrich leads.
• Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

1. Create queue agentnest-jobs with dead-letter subqueue.
2. build AgentJobWorker hosted service with peek-lock.
3. Complete message only after agent success; abandon on retryable errors.
4. Priority subqueues for hospital vs CRM jobs.
5. Schedule delayed messages for off-peak ERP batches.

Remember

Offload long agent work to Service Bus queues. Use MessageId idempotency and peek-lock processing. Monitor dead-letter queue for poison jobs.

Bulk lead enrichment

Marketing imports 50k leads; API enqueues jobs instead of timing out.

Outcome: Workers process overnight; CRM UI shows progress from queue depth metric.
