EFUnitOfWorkFactory 初始化

我正在尝试初始化 EFUnitOfWorkFactory 对象上下文。

在 global.asax 中：

void Application_Start(object sender, EventArgs e)
{
    // Code that runs on application startup
    ObjectFactory.Initialize(x =>
        {
            x.For<IUnitOfWorkFactory>().Use<EFUnitOfWorkFactory>();
            x.For(typeof(IRepository<>)).Use(typeof(EFRepository<>));
        }
    );
    EFUnitOfWorkFactory.SetObjectContext(() => new MyEntities());
}

在生成的对象上下文中，我有：

public partial class MyEntities : ObjectContext
{
    .....
    .....
}

当我在 EFUnitOfWorkFactory.SetObjectContext(() => new MyEntities()); 中执行 Web 应用程序时出现异常：

Compiler Error Message: CS0012: The type 'System.Data.Objects.ObjectContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

我添加了 System .Data.Entity 到我的网络应用程序两次并重建，但我仍然收到此消息。另外，gobal.asax 中的这一行有时会标有红色下划线。

有谁知道如何解决这个问题？

I am trying to initialize the EFUnitOfWorkFactory object context.

In global.asax:

void Application_Start(object sender, EventArgs e)
{
    // Code that runs on application startup
    ObjectFactory.Initialize(x =>
        {
            x.For<IUnitOfWorkFactory>().Use<EFUnitOfWorkFactory>();
            x.For(typeof(IRepository<>)).Use(typeof(EFRepository<>));
        }
    );
    EFUnitOfWorkFactory.SetObjectContext(() => new MyEntities());
}

In the generated Object context I have:

public partial class MyEntities : ObjectContext
{
    .....
    .....
}

I get an exception when I execute the web application in EFUnitOfWorkFactory.SetObjectContext(() => new MyEntities());:

Compiler Error Message: CS0012: The type 'System.Data.Objects.ObjectContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

I added System.Data.Entity to my web application twice and rebuild but I still get this message. In addition, this line in the gobal.asax smetimes marked with red underline.

Does anyone knows how to solve this?

您确定 Web 应用程序或网站中引用的程序集中有来自 .NET 4.0 的 System.Data.Entity.dll 吗？它也应该出现在 web.config 中：

<system.web>
  <compilation debug="true" targetFramework="4.0">
    <assemblies>
      <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    </assemblies>
  </compilation>

  ...
</system.web>

Are you sure that you have System.Data.Entity.dll from .NET 4.0 in your referenced assemblies in the web application or web site? It should also appear in web.config:

<system.web>
  <compilation debug="true" targetFramework="4.0">
    <assemblies>
      <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    </assemblies>
  </compilation>

  ...
</system.web>
