本文探讨了在ASP.NET MVC项目中如何合理地组织代码，包括扩展方法、辅助类等的存放位置，以及Entity Framework的使用方式。作者指出，不同于Web Forms中的App_Code，MVC项目中的代码可以更灵活地放置，并推荐使用独立的类库来组织共享代码。

问题:

In ASP.NET Webform, App_Code is standardfolder to putting code and using it at run-time.But I think this folder is kind of different in ASP.NET MVC, my question is:

where should I put my code ( Extension methods , Helpers , ... ) in ASP.NET MVC. When I store code in App_Code folder, I can't use theme in controller but they work fine in views.
About Entity Framework, the same question, where should I put edmx and tt files. I'm not using Code-First

Update:

After some search, finally I created a new Class Library project in my solution, code is available in allcontrollers and views. I still don't know why the code in App_Code is not available in controller

回答 :

App_Code is necessary in Web Site projects because it has a special meaning. It means "Don't serve these files to a web browser". In ASP.NET MVC, files are not directly served to the browser in most cases, so App_Code is not necessary. You can place code files whereever you want, in any folder you want.

Using a stand-alone library is also a fine solution.
