实体框架是否绑定到SQL Server？

Question

如果我想连接到Oracle，MySQL甚至MS Access，该怎么办？

Answer 1

No. It uses the ADO.Net "provider" model to plug in a database provider to give access to any third party database.

A list of available third party EF providers is here .

And here's an example of a prototype Oracle provider with source code.

Answer 2

One of the problem with the Entity Framework, is that Microsoft does not provide “providers” for 3rd party databases it's self. At present I don't think Oracle provides a “provider” for the Entity Framework, so if you wish to use the Entry Framework with Oracle you have to buy in a “provider”.
