Can I have entity looking like this?

public class Customer

{

private readonly List<Order> _orders = new List<Order>();

public string CustomerID { get; set; }

public string ContactName { get; set; }

public string City { get; set; }

public List<Order> Orders { get{return _orders}; }

public bool HasOrders {get {return Orders.Count>0;}}

}

@ Krzysztof

Yes your entity can look like that. We will support collection properties with getters only, or with both a getter and a setter. Anything that is an ICollection<T> will do.

Eagerly awaiting this release. I have just gotten comfortable with EFPocoAdapter so the migration isn't too tedious. And definitely looking forward to MSDN articles and better support (though Jarek has been quite responsive over email, I really was starting to miss full support)

My biggest pain point has to be serialization. I ran into a bunch of issues with circular references and JSON serialization before finally getting it working. Since the POCO classes are auto-generated I would like to see support to dynamically ignore properties during serialization (attributes only work at compile time and get overridden each time those classes are regenerated). This way

Would it be a bad idea to make those classes partial? I know that extending them would mean they're not purely POCO anymore but I do find that if they are auto-generated it's hard to modify them without getting your changes overridden. Extension methods work but only halfway through. Extension properties if that comes in .NET 4 might offer more flexibility in extending POCO objects.

That's great news. Although I feel you will still find cry babies, but EF finally starting to look good.

One important feature missing in this example is the ability to customize the generation of your entity classes. Using T4 you will be able to have POCO or whatever flavor of entity you desire by simply creating additional templates.

实体框架中的POCO体验

【译者按】 Entity Framework 1.0 发布也有一段时间了，但感觉用的人很少。其中一个很大的原因，也许就是不支持POCO。要知道，Entity Framework 1.0的做法是让你的实体从EF的基类继承而来

Hi,

I am trying to use ADO.Net Entity Data Framework in Prism. Almost all the examples including http://msdn.microsoft.com/en-us/library/cc838191(VS.95).aspx talk about Silverlight page accessing. However in our applications, we use modules which are Class Libraries or Silverlight Class Libraries, which bind the data to the UI. Are there any code samples/snippets to use the same?

Have uploaded the code sample at http://cid-8f83691dd01b3d44.skydrive.live.com/self.aspx/Prism/prismapp.v3.zip
