MvcScaffolding 创建未处置的一次性资源
将 MvcScaffolding 与 EF4.1 一起使用，我发现控制器的第一行生成通常是以下字段定义：
public class FooController : Controller
{
private BarContext context = new BarContext();
//.....
其中 BarContext 如下：
public class BarContext : System.Data.Entity.DbContext
鉴于 System.Data.Entity.DbContext< /code> 实现了 IDisposable，我很惊讶没有在 FooController 中找到任何可能处理的 Dispose(bool) 方法生成的重写处置上下文。
这是模板中的疏忽，还是我遗漏了一些东西，使得这不再是问题？
Using MvcScaffolding with EF4.1, I see that the first generated line of a Controller generally is the following field definition:
public class FooController : Controller
{
private BarContext context = new BarContext();
//.....
where BarContext is as follows:
public class BarContext : System.Data.Entity.DbContext
Given that System.Data.Entity.DbContext implements IDisposable, I am surprised not to find any generated override in FooController for the Dispose(bool) method that might take care of disposing context.
Is this an oversight in the templates, or is there something I'm missing that makes this a non-issue?

不，您没有丢失任何内容，您确实需要重写 Dispose，如本 EF 教程中所述：
No, you are not missing anything, you do need to override Dispose, as described in this EF tutorial:
http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/implementing-basic-crud-functionality-with-the-entity-framework-in-asp-net-mvc-application
The built-in scaffolding in MVC 3 Tools Update does generate the override (pre-release versions did not but the released version does), as noted in the tutorial. If the NuGet MvcScaffolding package does not do it, that is an oversight.
