Trackable DTO’s: Taking N-Tier a Step Further with EF4
This week I implemented Trackable Data Transfer Objects with EF4 using the same basic architecture that I wrote about in the article. I use two sets of T4 templates (a code-generation technology built into Visual Studio): One set is used by the Data Access Layer on the service side to generate both the ObjectContext container class and POCO classes that serve as DTO’s but have an ObjectState property. On the client side there is an assembly Download code for this post here .
Not long ago my friend and colleague Richard Blewett wrote a blog post on Self-Tracking Entities

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). These objects should be Plain Old CLR Objects (POCOs) that are Persistent Ignorant (PI), eschewing traces of any particular persistence technology. (How’s However, after searching for a few hours, I could not find any templates to generate POCOs. How’s that for an alphabet soup of acronyms?!) 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

WPF Data Providers
against an object and it's methods
XmlDataProvider: loads an XML data source and makes it available
NET object, then the
We could clearly do all of this from procedural code -- create an XmlReader object,
the data is really an XmlNode object which the ListBox has no idea how to display.
One of the nifty new features of the WPF platform is the pluggable data providers.
It ships with two out of the box:

EF 4.0 N-Tier Support: Take 2
The difference is that EF uses code-generation via T4 templates to create the helper classes instead of incorporating them into assemblies for the client and service to reference. The reason is that T4 templates are totally open-source. If I don’t like what they did or want to change it in any way, all I have to do is create my own version of the template.

Top Ten New Features in Entity Framework 4.0
SP1) generated a fair amount of criticism , especially because it lacked many features present in LINQ to SQL, such as POCO (Plain Old CLR Objects) support, and required developers to write excessive amounts of code to deal with things like concurrency and n-tier scenarios.
Define your own objects that are completely decoupled from persistence concerns.
The Entity Framework team at Microsoft has been extremely busy this past year to get a new version of the Entity Framework out the door. The first release (which shipped last summer with .NET
