Entity Framework 6.1 Learning Series overview, installation

Entity Framework: A solid frame that looks at the name to know about the model data. This is an ORM tool introduced by Ms.

Comparison with NHibernate

1) Entity Framework package better, add, delete, change, query more convenient

2) The Entity Framework uses a more convenient LINQ to Entity query, deferred loading (loading only when needed, loading only the required data).

3) Development efficiency is very high, using dbfirst almost without editing what code can generate a simple, general-purpose application.

The level is limited, just the recent experience about the Entity Framework learning to tidy up. For later inquiries
