• Has one class inheriting from DbContext.

  • Each property is decorated with needed data annotations.

Services:

• Each service has common methods (GetList(), Find(), Create(), etc.).

Business:

• Called from clients, orchestrate using services to perform a specific task UserChangePassword (this will check if this can be performed, then perform the task, or return error/unauthorized statuses among many others to make the client shows the correct information regarding the task. This on my case is where I log.

Clients (Desktop/Web/Wpf/etc).

I'm not saying this is the best approach, I'm just sharing what's been working for me.
