Can Entity Framework generate the DAL code?

I know t开发者_开发知识库hat entity framework has a database first approach. Now the question is whether it can generate the DAL (data access layer) code (not the models) for me.

When using a Object Relational Mapper (ORM), you don't typically have CRUD code in the traditional sense. Rather, it abstracts those operations into more object oriented operations.

For example, you don't "insert", you add the model class to the table, then save changes. The ORM automatically generates the SQL needed to make the Object model match the data model.

So my point is, your question displays a basic lack of understanding of how ORM's work and how they relate to data models. You should probably do a little reading.

I'm not sure what you mean specifically by "DAL code", as that's a rather ambiguous term. I would consider your Entity types part of the DAL.

When you use a model-first or database-first approach, the Entity Framework tools can auto-generate a context class from your model .edmx, which will inherit from ObjectContext. It's easy to customize the generated context class with T4 templates by finding one online that already generates from a .edmx, and modifying to your liking.

Code-first development uses the DbContext, which is not typically auto-generated. Please see this post on Scott Gu's blog for more details on this.
