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 methodology in my new applications. Where I'm struggling is finding a clear, concise beginners guide for EF4 which doesn't assume knowledge of EF1. The specific questions I need answered are: Code first / model first? Pros/cons in regards to EF4 (ie what happens if I

I'm trying to use the Repository Pattern with EF4 using VS2010. To this end I am using POCO code generation by right clicking on the entity model designer and clicking Add code generation item. I then select the POCO template and get my classes. What I would like to be able to do is have my solution structured into separate projects for Entity (POCO) classes and another project for the entity model and repository code. This means that my MVC project could use the POCO classes for strongly typed views etc and not have to know about the repository or have to have a reference to it. To plug it

Poco Exception提供的宏挺方便的。。 #include " Poco/Exception.h " #include <iostream> POCO_DECLARE_EXCEPTION( , MyException, Poco::Exception ) POCO_DECLARE_EXCEPTION( , MyFatalException, Poco::Exception ) POCO_IMPLEMENT_EXCEPTION( MyException, Poco::Exception, " Something really bad happened...

So I used this tutorial to generate my poco classes which I am to use throughout my aplication.. the problem is that Im not supposed to modify the generated cs files cause they get autoregenerated... How do I add attributes like [Required] and stuff like that?? please help You can't add it directly (unless you modify T4 template to create them for you) but you can try to use trick introduced in ASP.NET dynamic data. All POCO classes are defined as partial. So lets define your partial part: using System.ComponentModel.DataAnnotations; [MetadataType(typeof(MyClassMetadata))] public partial class
