NServiceBus has the concept of a pipeline execution order that is executed when a message is received or dispatched. A pipeline refers to the series of actions taken when an incoming message is processed or an outgoing message is sent. This allows users to take full control of the incoming and outgoing message processing.

There are two explicit pipelines: one for the outgoing messages and one for the incoming messages.

Each pipeline is composed of steps. A step is an identifiable value in the pipeline used to programmatically define order of execution. Each step represents a behavior which will be executed at the given place within the pipeline. To add additional behavior to the pipeline by registering a new step or replace the behavior of an existing step with the custom implementation.
