存储库模式，EF与存储过程

Question

We are pretty new to Entity Framework and the repository pattern, however trying to implement this into our system.

We have a domain model (logical model) built which our system will work with, which is fine. The issue is we are struggling to understand how we map the returned data from a stored procedure to this domain model.

The returned data from the stored procedure doesn't map to the entity model.

The only way I can think of doing this is purely by just executing the data reader, looping through the datareader, and assign each item directly, which seems dated...

From a google search "DataMapping" seems to appear, however, cannot see any examples of how to implement this from a stored procedure to a domain model, only stored procedure to entity model.

Let me ask a question.

If you had decided to use plain ADO.NET to do the mapping, would you have been done by now? Had everyone in the team understood to 100% what the code did?

Sometimes we just seem to try to apply new technology without really understanding why and what benefit it gives us. What advantage have you seen with Entity Framework? What kind of time saving do you see in version 1 contra version 5 of your application? What happens if the ORM fails? Will everyone in your team know why it fails?

If you are just using stored procedures it might be better to keep it simple (ADO.NET) or using a more lightweight mapper like Dapper or Massive .
