Switching from entity framework model first to code first

Question

I'm working on a project using entity framework 6. At the start of the project I was a beginner with EF and choose to build with EF model first.

Now the model is quite big and I’m thinking about performance and ease to change the model without dropping the databases every time.

I thinking about switching to code first.

Given that model first has already generated all the classes I need and context, I don't think it's that difficult to switch to code first.

Nevertheless I would like to know what would be the best way to do that and if there will be real advantage in term of performance and ease of model modification.

Thanks for your help,

I believe you will still have to drop the DB when your models change no matter what. (though I hear there is a migration tool to update, but try this old thing called design, - think what you need before you start!) — gbjbaanb

performance of model is a separate question.eg msdn.microsoft.com/en-us/data/dn469601 see the EF site for more tips and ideas msdn.microsoft.com/en-us/data/ee712907 — phil soady

EF 6.1 tooling now allows creating a Code First model from the database. Here is a short video and a walkthrough showing the functionality. You can download the latest EF tooling from the download center.

The code created by EDMX is not same as Fluent API although it is closed to Data Annotations.

If you would like to work with Fluent API, you can use Entity Framework Power Tools Beta 4 to generate to Fluent API from Database.
