We will walk through a modified example of a basic saga, originally from https://github.com/jkillingsworth/NServiceBus-BasicSagas. However, this example has been modified to use NHibernate, which uses a local SQL Express database. NHibernate was added using some of the steps from http://docs.particular.net/nservicebus/relational-persistence-using-nhibernate---nservicebus-4.x. We also added logging using the NLog framework to log functionalities as we go. The NHibernate ORM framework was chosen because it can connect to a multitude of different databases using the same code, the difference being the connection string in the app.config file for the different databases.

To elaborate on this saga example, there is a MySaga program that directs the messages while saving a saga instance as the messages are being moved. The saga persistence keeps track of the information that we defined to be saved in a saga entity object. The saga acts as an anchor that we can persist...
