Azure Servicebus Dotnet

Azure.Messaging.ServiceBus (.NET)

Overview

This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/azure-servicebus-dotnet from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

Azure.Messaging.ServiceBus (.NET) Enterprise messaging SDK for reliable message delivery with queues, topics, subscriptions, and sessions.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Environment Variables, Authentication, Client Hierarchy, Error Handling, Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• This skill is applicable to execute the workflow or actions described in the overview.
• Use when the request clearly matches the imported source intent: Azure Service Bus SDK for .NET. Enterprise messaging with queues, topics, subscriptions, and sessions.
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.
• Use when copied upstream references, examples, or scripts materially improve the answer.
• Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

Current Version: v7.20.1 (stable)

Imported: Core Workflows

1. Send Messages

await using ServiceBusClient client = new(fullyQualifiedNamespace, new DefaultAzureCredential());
ServiceBusSender sender = client.CreateSender("my-queue");

// Single message
ServiceBusMessage message = new("Hello world!");
await sender.SendMessageAsync(message);

// Safe batching (recommended)
using ServiceBusMessageBatch batch = await sender.CreateMessageBatchAsync();
if (batch.TryAddMessage(new ServiceBusMessage("Message 1")))
{
    // Message added successfully
}
if (batch.TryAddMessage(new ServiceBusMessage("Message 2")))
{
    // Message added successfully
}
await sender.SendMessagesAsync(batch);

2. Receive Messages

ServiceBusReceiver receiver = client.CreateReceiver("my-queue");

// Single message
ServiceBusReceivedMessage message = await receiver.ReceiveMessageAsync();
string body = message.Body.ToString();
Console.WriteLine(body);

// Complete the message (removes from queue)
await receiver.CompleteMessageAsync(message);

// Batch receive
IReadOnlyList<ServiceBusReceivedMessage> messages = await receiver.ReceiveMessagesAsync(maxMessages: 10);
foreach (var msg in messages)
{
    Console.WriteLine(msg.Body.ToString());
    await receiver.CompleteMessageAsync(msg);
}

3. Message Settlement

// Complete - removes message from queue
await receiver.CompleteMessageAsync(message);

// Abandon - releases lock, message can be received again
await receiver.AbandonMessageAsync(message);

// Defer - prevents normal receive, use ReceiveDeferredMessageAsync
await receiver.DeferMessageAsync(message);

// Dead Letter - moves to dead letter subqueue
await receiver.DeadLetterMessageAsync(message, "InvalidFormat", "Message body was not valid JSON");

4. Background Processing with Processor

ServiceBusProcessor processor = client.CreateProcessor("my-queue", new ServiceBusProcessorOptions
{
    AutoCompleteMessages = false,
    MaxConcurrentCalls = 2
});

processor.ProcessMessageAsync += async (args) =>
{
    try
    {
        string body = args.Message.Body.ToString();
        Console.WriteLine($"Received: {body}");
        await args.CompleteMessageAsync(args.Message);
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Error processing: {ex.Message}");
        await args.AbandonMessageAsync(args.Message);
    }
};

processor.ProcessErrorAsync += (args) =>
{
    Console.WriteLine($"Error source: {args.ErrorSource}");
    Console.WriteLine($"Entity: {args.EntityPath}");
    Console.WriteLine($"Exception: {args.Exception}");
    return Task.CompletedTask;
};

await processor.StartProcessingAsync();
// ... application runs
await processor.StopProcessingAsync();

5. Sessions (Ordered Processing)

// Send session message
ServiceBusMessage message = new("Hello")
{
    SessionId = "order-123"
};
await sender.SendMessageAsync(message);

// Receive from next available session
ServiceBusSessionReceiver receiver = await client.AcceptNextSessionAsync("my-queue");

// Or receive from specific session
ServiceBusSessionReceiver receiver = await client.AcceptSessionAsync("my-queue", "order-123");

// Session state management
await receiver.SetSessionStateAsync(new BinaryData("processing"));
BinaryData state = await receiver.GetSessionStateAsync();

// Renew session lock
await receiver.RenewSessionLockAsync();

6. Dead Letter Queue

// Receive from dead letter queue
ServiceBusReceiver dlqReceiver = client.CreateReceiver("my-queue", new ServiceBusReceiverOptions
{
    SubQueue = SubQueue.DeadLetter
});

ServiceBusReceivedMessage dlqMessage = await dlqReceiver.ReceiveMessageAsync();

// Access dead letter metadata
string reason = dlqMessage.DeadLetterReason;
string description = dlqMessage.DeadLetterErrorDescription;
Console.WriteLine($"Dead letter reason: {reason} - {description}");

7. Topics and Subscriptions

// Send to topic
ServiceBusSender topicSender = client.CreateSender("my-topic");
await topicSender.SendMessageAsync(new ServiceBusMessage("Broadcast message"));

// Receive from subscription
ServiceBusReceiver subReceiver = client.CreateReceiver("my-topic", "my-subscription");
var message = await subReceiver.ReceiveMessageAsync();

8. Administration (CRUD)

var adminClient = new ServiceBusAdministrationClient(
    fullyQualifiedNamespace,
    new DefaultAzureCredential());

// Create queue
var options = new CreateQueueOptions("my-queue")
{
    MaxDeliveryCount = 10,
    LockDuration = TimeSpan.FromSeconds(30),
    RequiresSession = true,
    DeadLetteringOnMessageExpiration = true
};
QueueProperties queue = await adminClient.CreateQueueAsync(options);

// Update queue
queue.LockDuration = TimeSpan.FromSeconds(60);
await adminClient.UpdateQueueAsync(queue);

// Create topic and subscription
await adminClient.CreateTopicAsync(new CreateTopicOptions("my-topic"));
await adminClient.CreateSubscriptionAsync(new CreateSubscriptionOptions("my-topic", "my-subscription"));

// Delete
await adminClient.DeleteQueueAsync("my-queue");

9. Cross-Entity Transactions

var options = new ServiceBusClientOptions { EnableCrossEntityTransactions = true };
await using var client = new ServiceBusClient(connectionString, options);

ServiceBusReceiver receiverA = client.CreateReceiver("queueA");
ServiceBusSender senderB = client.CreateSender("queueB");

ServiceBusReceivedMessage receivedMessage = await receiverA.ReceiveMessageAsync();

using (var ts = new TransactionScope(TransactionScopeAsyncFlowOption.Enabled))
{
    await receiverA.CompleteMessageAsync(receivedMessage);
    await senderB.SendMessageAsync(new ServiceBusMessage("Forwarded"));
    ts.Complete();
}

Examples

Example 1: Ask for the upstream workflow directly

Use @azure-servicebus-dotnet to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @azure-servicebus-dotnet against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @azure-servicebus-dotnet for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @azure-servicebus-dotnet using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Use singletons — Clients, senders, receivers, and processors are thread-safe
• Always dispose — Use await using or call DisposeAsync()
• Dispose order — Close senders/receivers/processors first, then client
• Use DefaultAzureCredential — Prefer over connection strings for production
• Use processors for background work — Handles lock renewal automatically
• Use safe batching — CreateMessageBatchAsync() and TryAddMessage()
• Handle transient errors — Use ServiceBusException.Reason

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills-claude/skills/azure-servicebus-dotnet, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.
