Receive Messages\n\n```csharp\nServiceBusReceiver receiver = client.CreateReceiver(\"my-queue\");\n\n\u002F\u002F Single message\nServiceBusReceivedMessage message = await receiver.ReceiveMessageAsync();\nstring body = message.Body.ToString();\nConsole.WriteLine(body);\n\n\u002F\u002F Complete the message (removes from queue)\nawait receiver.CompleteMessageAsync(message);\n\n\u002F\u002F Batch receive\nIReadOnlyList\u003CServiceBusReceivedMessage> messages = await receiver.ReceiveMessagesAsync(maxMessages: 10);\nforeach (var msg in messages)\n{\n    Console.WriteLine(msg.Body.ToString());\n    await receiver.CompleteMessageAsync(msg);\n}\n```\n\n### 3. Message Settlement\n\n```csharp\n\u002F\u002F Complete - removes message from queue\nawait receiver.CompleteMessageAsync(message);\n\n\u002F\u002F Abandon - releases lock, message can be received again\nawait receiver.AbandonMessageAsync(message);\n\n\u002F\u002F Defer - prevents normal receive, use ReceiveDeferredMessageAsync\nawait receiver.DeferMessageAsync(message);\n\n\u002F\u002F Dead Letter - moves to dead letter subqueue\nawait receiver.DeadLetterMessageAsync(message, \"InvalidFormat\", \"Message body was not valid JSON\");\n```\n\n### 4. Background Processing with Processor\n\n```csharp\nServiceBusProcessor processor = client.CreateProcessor(\"my-queue\", new ServiceBusProcessorOptions\n{\n    AutoCompleteMessages = false,\n    MaxConcurrentCalls = 2\n});\n\nprocessor.ProcessMessageAsync += async (args) =>\n{\n    try\n    {\n        string body = args.Message.Body.ToString();\n        Console.WriteLine($\"Received: {body}\");\n        await args.CompleteMessageAsync(args.Message);\n    }\n    catch (Exception ex)\n    {\n        Console.WriteLine($\"Error processing: {ex.Message}\");\n        await args.AbandonMessageAsync(args.Message);\n    }\n};\n\nprocessor.ProcessErrorAsync += (args) =>\n{\n    Console.WriteLine($\"Error source: {args.ErrorSource}\");\n    Console.WriteLine($\"Entity: {args.EntityPath}\");\n    Console.WriteLine($\"Exception: {args.Exception}\");\n    return Task.CompletedTask;\n};\n\nawait processor.StartProcessingAsync();\n\u002F\u002F ... application runs\nawait processor.StopProcessingAsync();\n```\n\n### 5. Sessions (Ordered Processing)\n\n```csharp\n\u002F\u002F Send session message\nServiceBusMessage message = new(\"Hello\")\n{\n    SessionId = \"order-123\"\n};\nawait sender.SendMessageAsync(message);\n\n\u002F\u002F Receive from next available session\nServiceBusSessionReceiver receiver = await client.AcceptNextSessionAsync(\"my-queue\");\n\n\u002F\u002F Or receive from specific session\nServiceBusSessionReceiver receiver = await client.AcceptSessionAsync(\"my-queue\", \"order-123\");\n\n\u002F\u002F Session state management\nawait receiver.SetSessionStateAsync(new BinaryData(\"processing\"));\nBinaryData state = await receiver.GetSessionStateAsync();\n\n\u002F\u002F Renew session lock\nawait receiver.RenewSessionLockAsync();\n```\n\n### 6. Dead Letter Queue\n\n```csharp\n\u002F\u002F Receive from dead letter queue\nServiceBusReceiver dlqReceiver = client.CreateReceiver(\"my-queue\", new ServiceBusReceiverOptions\n{\n    SubQueue = SubQueue.DeadLetter\n});\n\nServiceBusReceivedMessage dlqMessage = await dlqReceiver.ReceiveMessageAsync();\n\n\u002F\u002F Access dead letter metadata\nstring reason = dlqMessage.DeadLetterReason;\nstring description = dlqMessage.DeadLetterErrorDescription;\nConsole.WriteLine($\"Dead letter reason: {reason} - {description}\");\n```\n\n### 7. Topics and Subscriptions\n\n```csharp\n\u002F\u002F Send to topic\nServiceBusSender topicSender = client.CreateSender(\"my-topic\");\nawait topicSender.SendMessageAsync(new ServiceBusMessage(\"Broadcast message\"));\n\n\u002F\u002F Receive from subscription\nServiceBusReceiver subReceiver = client.CreateReceiver(\"my-topic\", \"my-subscription\");\nvar message = await subReceiver.ReceiveMessageAsync();\n```\n\n### 8. Administration (CRUD)\n\n```csharp\nvar adminClient = new ServiceBusAdministrationClient(\n    fullyQualifiedNamespace, \n    new DefaultAzureCredential());\n\n\u002F\u002F Create queue\nvar options = new CreateQueueOptions(\"my-queue\")\n{\n    MaxDeliveryCount = 10,\n    LockDuration = TimeSpan.FromSeconds(30),\n    RequiresSession = true,\n    DeadLetteringOnMessageExpiration = true\n};\nQueueProperties queue = await adminClient.CreateQueueAsync(options);\n\n\u002F\u002F Update queue\nqueue.LockDuration = TimeSpan.FromSeconds(60);\nawait adminClient.UpdateQueueAsync(queue);\n\n\u002F\u002F Create topic and subscription\nawait adminClient.CreateTopicAsync(new CreateTopicOptions(\"my-topic\"));\nawait adminClient.CreateSubscriptionAsync(new CreateSubscriptionOptions(\"my-topic\", \"my-subscription\"));\n\n\u002F\u002F Delete\nawait adminClient.DeleteQueueAsync(\"my-queue\");\n```\n\n### 9. Cross-Entity Transactions\n\n```csharp\nvar options = new ServiceBusClientOptions { EnableCrossEntityTransactions = true };\nawait using var client = new ServiceBusClient(connectionString, options);\n\nServiceBusReceiver receiverA = client.CreateReceiver(\"queueA\");\nServiceBusSender senderB = client.CreateSender(\"queueB\");\n\nServiceBusReceivedMessage receivedMessage = await receiverA.ReceiveMessageAsync();\n\nusing (var ts = new TransactionScope(TransactionScopeAsyncFlowOption.Enabled))\n{\n    await receiverA.CompleteMessageAsync(receivedMessage);\n    await senderB.SendMessageAsync(new ServiceBusMessage(\"Forwarded\"));\n    ts.Complete();\n}\n```\n\n## Key Types Reference\n\n| Type | Purpose |\n|------|---------|\n| `ServiceBusClient` | Main entry point, manages connection |\n| `ServiceBusSender` | Sends messages to queues\u002Ftopics |\n| `ServiceBusReceiver` | Receives messages from queues\u002Fsubscriptions |\n| `ServiceBusSessionReceiver` | Receives session messages |\n| `ServiceBusProcessor` | Background message processing |\n| `ServiceBusSessionProcessor` | Background session processing |\n| `ServiceBusAdministrationClient` | CRUD for queues\u002Ftopics\u002Fsubscriptions |\n| `ServiceBusMessage` | Message to send |\n| `ServiceBusReceivedMessage` | Received message with metadata |\n| `ServiceBusMessageBatch` | Batch of messages |\n\n## Best Practices\n\n1. **Use singletons** — Clients, senders, receivers, and processors are thread-safe\n2. **Always dispose** — Use `await using` or call `DisposeAsync()`\n3. **Dispose order** — Close senders\u002Freceivers\u002Fprocessors first, then client\n4. **Use DefaultAzureCredential** — Prefer over connection strings for production\n5. **Use processors for background work** — Handles lock renewal automatically\n6. **Use safe batching** — `CreateMessageBatchAsync()` and `TryAddMessage()`\n7. **Handle transient errors** — Use `ServiceBusException.Reason`\n8. **Configure transport** — Use `AmqpWebSockets` if ports 5671\u002F5672 are blocked\n9. **Set appropriate lock duration** — Default is 30 seconds\n10. **Use sessions for ordering** — FIFO within a session\n\n## Error Handling\n\n```csharp\ntry\n{\n    await sender.SendMessageAsync(message);\n}\ncatch (ServiceBusException ex) when (ex.Reason == ServiceBusFailureReason.ServiceBusy)\n{\n    \u002F\u002F Retry with backoff\n}\ncatch (ServiceBusException ex)\n{\n    Console.WriteLine($\"Service Bus Error: {ex.Reason} -
