Nhibernate hasmany not updating ball carbon cold curve dating fusion

No mappings are actually generated until we push them into NHibernate, this gives us opportunity to customise them before-hand, which we'll go into later.

We're going to utilise the fluent configuration API to create our that you've configured elsewhere, we're just doing it in-line for brevity.

There are still scenarios where it may not be suitable to use the auto mapping, at which point it would be more appropriate to use the Fluent mapping; however, for most greenfield applications (and quite a few brownfield ones too) auto mapping will be more than capable.

that's tied to the assembly that Product is declared.

Anyway, look at the two entities, the two mapping files, the four conventions, and then lastly, the single controller.

Auto mapping utilises the principle of convention over configuration.

Using this principle, the auto mapper inspects your entities and makes assumptions of what particular properties should be.

This is some winforms code which combines controller and view.
