Message brokers:
Below are the message service brokers. those are used to store messages and consume the messages
and each broker has some other features.
1. MSMQ
2. RabbitMQ
3. Azure Service Bus
MSMQ- Microsoft Message Queuing
1. MSMQ is a message queue implementation developed by Microsoft.
2. It deployed in its Windows Server operating systems.
3. It is a messaging protocol.
4. MSMQ ensures reliable delivery by placing messages that fail to reach their intended destination
in a queue and then resending them once the destination is reachable.
5. MSMQ also supports transactions.
https://docs.microsoft.com/en-us/dotnet/framework/wcf/samples/net-msmq-binding
Dead Queues:
1. Handel process messages that have failed delivery (undeliverable, deleted, expired etc)
2. It support by using Net Binding - Net MSMQ Binding - Dead letter queue
3. About net msmq binding, end point and binding configuration and contract is explained in the below url
4. Message that is sent to a queue that does not exist.
5. Queue length limit exceeded.
6. Message length limit exceeded.
7. Message is rejected by another queue exchange.
https://docs.microsoft.com/en-us/dotnet/framework/wcf/samples/dead-letter-queues
Poison Message: -- Limited support
1. Poison Message Handling in MSMQ 4.0
2. Schedule a message
3. Read the message repeatedly from queue when it failed
4. Based on the version of MSMQ, the NetMsmqBinding supports limited detection to full detection of poison messages.

Session and Queues:
Group of messages is processed by single request
Queued sessions are a mechanism used to send and receive a related set of messages that must get processed all at once.
a client sends a set of messages that are related to each other in a group. When messages must be processed together or in a specified order, a queue can be used to group them together, for processing by a single receiving application
Volatile Message:
msmq - makes to best effort to deliver the message(success/failure) with no assurances.
You may want to send a volatile message with no assurances over a queue, when timely delivery is more important than losing messages. Volatile messages do not survive queue manager crashes. Therefore if the queue manager crashes, the non-transactional queue used to store volatile messages survives
You cannot send volatile messages with no assurances within the scope of a transaction using MSMQ. You also must create a non-transactional queue to send volatile messages.
By using Net MSMQ - Dotnet - WCF - We can achieve below features
1. Two - way communication
2. Dead letter queue
3. Poison message
4. Message security
5. Session and Queues
RabbitMQ:
https://www.rabbitmq.com/
1. RabbitMQ is the most popular open source message broker.
2. Runs on many operating systems and cloud environments,
Features:
1. Asynchronous Messaging
2. Multiple messaging protocols
3. Message queuing
4. Delivery acknowledgement
5. Flexible routing to queues
6. Multiple exchange type.
7. Pluggable Authentication and Authorization.
8. By default supports - Transport Layer Security (TLS) is the successor protocol to SSL. TLS is an improved version of SSL.
9. supports LDAP to perform authentication and authorisation
