I am writing my first WPF and EF application. I am using SQL CE

  • 0

I am writing my first WPF and EF application. I am using SQL CE database and I have added few tables to the DB. The EF diagram is generated and now I want to generate the classes. I am new to EF and MVVM both.

When I right-click on a Table diagram, it gives option “Add Code Generation Item..”. On selecting it, there are two options:

Add Entity Object Generator

Add Self-Tracking Entity Object Generator

I want to know what is the difference between the two. Which one should I use? I also want to know which one is latest and what is POCO?

    A POCO is a Plain Old CLR Object… a simple class that has only properties.

    http://en.wikipedia.org/wiki/Plain_Old_CLR_Object

    There are 3 approaches that the Entity Framework delivers.

    • Model first (you create a model in visual studio and generate the database)
    • Database first (thats what you do, you generate a model from a existing database)
    • Code first (the newest one, you just write you POCOS and the entity framework generates the database)

    I think it is enough to generate the diagram from database. The context and models should be available after this.
