EF4 POCO: Snapshot vs Self-tracking over WCF
Hello Last year I developed a data access service for our project using Entity Framework (.NET3.5 of course) and using Julie Lerhman's book as a guide developed state tracking POCO objects.

Entity Framework 4.0: Create an unmapped property in the model (currenty i get : error 11009 - Property is not mapped)?
Hi there, I know that i can enter/add new properties via code manually into partial classes but i wanted to use the model to add my new properties - reason being is that i can control a number of different attributes like NULL and things like that... and of course the code generations works great.. I added some foreign keys manually ju...
Validating disconnected POCOs
In my ASP.NET application I have separate projects for the Data, Business and UI layers. My business layer is composed of plain objects with declarative validation, using DataAnnotations. Problem is, when it comes to save them, I'm not sure how to process the validation, since they're not bound directly to any data context, but rather,...
POCO in Entity Framework with snapshot change detection
Hi, I have a Visual Studio 2010 generated set of POCO classes (just out of the box POCO templates generated from DB Schema). For a given use case I let the user load an entity (a CRM contact) and act on it - add Phone Numbers (which in itself is a separate entity related by foreign key) and address (also a separate entity) etc. In bet...
How to leverage concurrency checking with EF 4.0 POCO Self Tracking Entities in a N-Tier scenario?
I'm using VS1010RC with the POCO self tracking T4 templates.

POCO Best Practice
All, I have a series of domain objects (project is NHibernate based). Currently as per 'good practice' they define only the business objects, comprising properties and methods specific to each objects function within the domain.

Entity Framework 4 / POCO - Where to start?
Hi, I've been programming for a while and have used LINQ-To-SQL and LINQ-To-Entities before (although when using entities it has been on a Entity/Table 1-1 relationship - ie not much different than L2SQL) I've been doing a lot of reading about Inversion of Control, Unit of Work, POCO and repository patterns and would like to use this m...
EDM -> POCO -> WCF (.NET4) But transferring Collections causes IsReadOnly set to TRUE
Ok, this may sound a little 'unorthodox', but...using VS2010 and the new POCO t4 template for Entity Framework (http://tinyurl.com/y8wnkt2), I can generate nice POCO's. I can then use these POCO's (as DTO's) in a WCF service essentially going from EDM all the way through to the client. Kinda what this guys is doing (http://tinyurl.com/yb...
What is PocoCapsule current status?
What is PocoCapsule current status? Is it evolving? Has it been forked with some other product? What is about the whole idea of IoC for C++? If PocoCapsule is not evolving, is it because IoC was considered not useful for C++, unsafe, other patterns appeared or something else? As far as I understand there are 2-3, maybe few more products...

How to normalize / refactor e-commerce tables to Pocos when the data is much like EAV.
In our e-commerce application, we have different kinds of products having different kinds of attributes, e.g., a shoe has different selling features than an edible cake. Our e-commerce site allows you to "build" your own products, selecting various attributes and values (like pink frosting on a cup cake which adds $.25 to the cost). Ou...
Different EF Property DataType than Storage Layer Possible?
Hi, I am putting together a WCF Data Service for PatientEntities using Entity Framework. My solution needs to address these requirements: Property DateOfBirth of entity Patient is stored in SQL Server as string. It would be ideal if the entity class did not also use the "string" type but rather a DateTime type. (I would expect this t...
