Trackable DTO’s: Taking N-Tier a Step Further with EF4
Not long ago my friend and colleague Richard Blewett wrote a blog post on Self-Tracking Entities in EF4, in which he questioned the service-orientation of Self-Tracking Entities in EF4. While STE’s are placed in an assembly that does not reference the Entity Framework, the way in which change state is preserved in an STE is overly complex because it tries make it easier for EF to transmit those changes to the ObjectStateManager on the service side. Download code for this post here . If you look closely at the ObjectChangeTracker class that is generated for

EF4 compared to NHibernate
Last week while teaching my new LINQ and Entity Framework course I got a question asking me to compare EF4 with NHibernate . EF is more than an ORM and supports a streaming model with data readers against the entity model without materializing entities EF supports LINQ out of the box (NH doesn’t have it yet) Not having worked extensively with NHibernate, I wasn’t in a position to address the question. Then yesterday I received an email containing a link to a blog post by Oren Eini (aka Ayende Rahien) doing just such a comparison.

  • Better N-Tier Concurrency Management for the Entity Framework
    I just wrote an article for MSDN Magazine (due out in December) about developing n-tier applications for both LINQ to SQL and the Entity Framework. While researching the topic, I noticed a certain awkwardness with the Entity Framework API when it came to managing concurrency with a timestamp fields, as compared with LINQ to SQL. The Entity Framework, on the other hand, requires attaching the original L2S has an overloaded Attach method that accepts a bool asModified parameter indicating the presence of a timestamp field used for concurrency. This

  • Faking Enums in Entity Framework 4.0
    I’ve had a great deal of experience using enums with LINQ to SQL (via Plinqo ), and it’s nice to know how to do it in EF, while waiting for the feature to come out-of-the-box in a future version. I ran across a great post from Alex James on how to fake enums in EF4. http://blogs.msdn.com/alexj/archive/2009/06/05/tip-23-how-to-fake-enums-in-ef-4.aspx
