Message Queues allows data exchange between one or more application and in the meantime, it won’t force the application being communicated should be in live connection. Application 1 can send a message and quit or do another task. Application 2 when free looks at the queue and catches the passed-in information.
MSMQ can maintain one or more queue. In the above picture, we can see three queues. We will develop a sample in this article, which will send and receive the information through the MSMQ as shown above. In our example, we will use only one queue, say Q1. However, one can create multiple queues based on the need.
