The developerdoc only shows adding custom property. I am wondering what is the best way in version 4.0 to add some custom entities.
1. Add a new folder Building
2. Add a custom class in Nop.Core.Domain.Building building.cs where i put in the file properties
3. Add a mapping file in [Project Root]\Libraries\Nop.Data\Mapping\Building buildingmap.cs
do the samething for the presentation layer.
Do i have to create my own SQL Files?
Do i have to update the emx file
Any thoughts, guides are welcome :-).
