Sorry for the Delay - Back on track, Microsoft's Entity Framework

Okay, so it's been awhile since I've blogged.  In addition to software development I own a small Beekeeping business and Spring is one of the craziest times of the year for beekeepers.  I've been working 90+ weeks for the past four weeks between my software gigs and bees so as you can see I've had very little time to keep my blog updated.

I'm currently working two different projects for two different organizations in which I'm using Entity Framework The first project is actually part of an application migration in which legacy data is being extracted from several legacy databases and being migrated/transitioned into an existing production database.  This project is using code first for the development and testing portions of the project. The second project involves using a WCF service which uses EF.  This second project allows me to define and create the both the domain class and database tables as I see fit.    Hopefully, I'll have a decent handle on EF after these two projects.

As I've been busy and focused on other work/projects I'm having to catch-up and remember where I left off on the first project. To help jog my memory I'm reviewing O'Reilly's Programming Entity Framework: Code First. Two other O'Reilly references that I will use, but haven't yet, are - Programming Entity Framework (2nd Edition) and Programming Entity Framework: DbContext.

For me, I need to remember the following definitions from the first couple of chapters.

• Domain Class - My application's object classes

• DbContext - Makes code first "aware" of my domain classes, wrapper around ObjectContext

• DbSet - Wrapper around ObjectSet

• EDMX - model XML, database XML, Mapping XML
