I have spent a fair amount of time already trying to improve my experience with the Entity Framework with versions 1.0, 2.0 and 3.0. Well that’s a bit of joke really because there was and never will be versions 2.0 or 3.0 for the Entity Framework with...

EF v2 and Data Access Architecture Best Practices

David Hill, in his preface to the latest patterns & practices Architecture Guidance, jokes that the key to being a good architect is learning to answer "It depends" to most questions. In this article, I'll take that joke to heart. How...

【翻译】实体框架中的POCO支持 - 第一部分 - 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，这对很多人，特别是崇尚DDD的人来说，那是一副难以下咽的药啊。曾有微软开发人员提供了一个 POCO Adapter ，但那究竟不是正规的做法。Visual Studio 2010 和 .NET 4.0 提供了许许多多的新特性，真是让人激动，向往，大有一种回到.NET 1.0 刚出来时的感觉...

Entity Framework 4.0 Beta 1 – POCO, ObjectSet, Repository and UnitOfWork
