Best way to approach tying in Entity Framework 4 ("Database First") and MVC3

I am a relative newcomer for C#.Net (.net 4), EF4, Winforms, and MVC3.

I had laid out a database in SQL Server in the process of developing a Winforms "backend" for a task I have been assigned. I setup a single Solution and created a .edmx from the database as its own project/assembly in the solution. Also in the solution is the winforms app that references the .edmx assembly. Using the default EF4 code generation, I built out the Winforms app and all is well there.

Now, I have to build out the enduser web frontend. I want to use MVC3. I have been through MVC3 tutorials on Pluralsight and fairly a decent understanding of MVC3 from that. But, both therein and elsewhere, most examples of MVC3+EF4 are "code first".

My confusion is what is the best approach to combine an EF4 Database-first with MVC3? I have looked some at EF4Templates, but, it seems these generate POCOs that are different than the default EF4 stuff and would break my Winforms app. I have read some on Repo开发者_开发问答sitories and the use of Automapper as well. I can add a reference to EF4 and my .edmx into the MVC3 project (same as I did with the Winforms), but it appears one still has to contruct a controller/view's model OR can one just work directly with the default EF4 classes in a controller?

Just seeking some guidance as to just how this has to be approached with respect to MVC3.

Thanks!

You could work directly with the default EF4 classes in a controller if you wanted. The tooling support in the MVC 3 Tools Update for adding and scaffolding controllers works with code first but you can also use an existing context from a .edmx if you want to work directly with the objects.

If you would rather use a repository pattern in your application you can check out the MvcScaffolding package, some info about it can be found on Steve Sanderson's blog.

You could also create view models yourself if you wanted to go that route.
