Code First, do you like it?

How about being really brave and discarding the relational model altogether[^]? (OK - possibly quite a big leap into the unknown...)
Interesting. Unfortunately, the world I live in revolves around "what can you give me in a certain time frame?". This does not lend itself well to theoretical software development, or hobby craft, where it may or may not work. Now, after a few years, and it has moved from philosophy into mainstream practice, then I would consider adopting. --> You used the phrase "may free us", in your linked page article, which has a certain level of uncertainty to me, hence the tone of my reply. :)

I'm working on a project right now and we used Code First. There's some nice stuff about it if you keep your database simple, but what database ever ends up being simple, right? Stuff like Migrations can make changes very easy to implement but others a real pain in the ass. If you've got a very small team, like under 5 people, Migrations can be easy to manage. If not, it can be a huge pain. It's probably best to keep the Migrations limited to just a few people on the team until the database is fleshed out. Multiple people putting in migrations on the same table at the same time can make your life miserable. We ran into a couple of problems like this and I'm one of two people working on this project. If you're going to have multiple people doing Migrations coordination of those changes is paramount. I can't stress that enough. If you want to avoid problems, you have to make sure no two people are making changes to the same table at the same time. You REALLY have to understand your data and how relationships work before you even think of starting with Code First. Code First isn't the best when determining how it's going to setup a relationship and you really have to know your DB stuff to make sure it's getting it correct. When Code First doesn't get a relationship correct or exactly the way you want it there is a rather steep learning curve to the syntax to configure it correctly and it only gets steeper if you don't know enough of the detail of how the database side works and the terminology involved. Would I use Code First again? Sure, but not for large projects. I'd keep it to smaller ones only.

Some industries (financial services, mobile phone billing etc.) are already using this model. Unfortunately the code we/they use is very proprietary and this kind of thing is not used in college courses (yet). Commercial offerings do exist - in particular Event Store[^]

Just saw a demo online a few days ago, and the "demo guys" were having trouble with some areas with code first, and they were the "experts". So far, I am not entirely convinced that it is a development strategy worth using for the long term. We shall see, I guess.

We are thinking about moving from database first, to code first, with our new projects.
I like it. Different from DB first, but the automatic db intialization is neat.

My buddy has it. Will post back with it when I get it. I watched part of the vid clip on his machine, not mine.

Too many times someone makes a "minor" tweak to one or the other and then forgets to regenerate, then you're hosed.
I have read, and heard, many stories about this. It is one of our concerns.
But how many times has someone updated one, and forgot to update the other? At least with auto-generation, you're one click away from regenerating. With code first, you need to sit down and verify every recent change to ensure it has been incorporated.

Learn ASP.NET Online – Microsoft Virtual Academy[^] Under "Creating and configuring models" --> Creating models --> around 23:40 but start at around 22:00 to get some intro context. I heard that the SNAFU they had during the demo happens a lot to people, especially those who are trying to get up to speed with "code first".

Thank you! Will take a look..

Light roast (mild flavor), has more caffeine than manly, dark roast. Just saying. :-D Although, I prefer the flavor of a medium roast to a Sumatra, etc..
Definitely prefer a Sumatra or French Roast.:suss:
My long term goal is to live forever. So far, so good...

I still prefer to design the database the traditional way, but the migrations that code first uses are pretty cool.
Can you elaborate on that please?

Frack no. It's the epitome of taking a very bad idea and following it ad absurdum.

Exactly; from what I see, the "latest and greatest shiniest new" tools are designed for a different demographic. :suss: If you don't know what you're doing, better have someone else do it for you.
