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

Survival Skills for Developers
Data access toolkit (homegrown or open source or commercial) If reading and writing from a database is a basic skill like walking, then a good data access framework is your walking stick. NET guy so I’ve worked with NHibernate, SubSonic, Entity Framework, and a couple homegrown solutions. Let’s suspend reality for a moment and pretend you’re heading out into the woods this weekend. Set aside the fact that you are a software developer and have no business tromping around out in the wilderness.

  • 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 unmodified entity, L2S has an overloaded Attach method that accepts a bool asModified parameter indicating the presence of a timestamp field used for concurrency.

  • Hot Off the Presses: SOA Data Access!
    I wrote an article for the December issue of MSDN Magazine, which has just hit the streets: The title is: Flexible Data Access With LINQ To SQL And The Entity Framework , and you can download the accompanying code here . The purpose of the article is to provide a practical approach for developing real-world data-driven applications with either LINQ to SQL or the Entity Framework that use a layered, n-tier architecture. Developers currently face daunting challenges when it comes to developing these types of applications, even though it is these types of apps are the bread and butter of what most developers do on a day-to-day basis.

  • T4 POCO Templates for L2S and EF
    In my MSDN Magazine article on SOA Data Access I recommend exposing Data Transfer Objects (DTOs) from the Data Access Layer (DAL). The point here is that the DAL truly encapsulates the API you’re using to fetch and update data, which makes it possible to swap out one data access stack for another without breaking the client. Having said all that, what tools are available to automatically generate POCO These objects should be Plain Old CLR Objects (POCOs) that are Persistent Ignorant (PI), eschewing traces of any particular persistence technology.
