See this answer. Ask yourself why you need Access, could you use SQL Express instead? If you absolutely need Access then it would seem EF is not the right choice in this instance.

Putting Access to one side for the moment, it's perfectly possible to change data providers with EF (particularly code-first) as EF abstracts a lot of the database goo away from your code; depending on the database design it could be as simple as changing the connection string dynamically. The practical implications of this really do depend on your database design and the nature and complexity of the application you are building. See this question for example, here's another example.

Answer 3

在使用 MS Access 时，我们使用 Dapper 作为我们的 ORM 和存储库。这是梦幻般的。
