Entity Framework from scratch

Hi,

I would like to know how nopCommerce team have generated the classes (POCOs?) and Contexts on their own structure of namespaces...there's any manual work? I am asking because examples I saw generated these classes under a .tt file or as partial classes under the .Designer.cs of the model file, and I could not find any of those in the solution and we are thinking about modeling the introduction of new entities.

Thanks

They are hand-crafted

Thanks for the reply.

So it means that EntityType attribute of NopModel.edmx is also hand-crafted?
I imagine that at first time, you generated the classes from database and then disabled the automatic generation, or something like this?

Another question, to complement the last one: what when you need to add a new attribute to some entity? You add the column to database (if needed), synchronize the model with database and than manually adds the new attribute (property) to the entity?

All of them were hand-crafted (previously we didn't use EF, and they already existed)
