asp.net-mvc – 无法使用Simple Injector为每个请求创建DbContex

The supplied connection string is not valid,because it contains insufficient mapping or metadata information.
Parameter name: connectionString

我是DI的新手,可能会遗漏一些相当明显的东西.连接字符串看起来很好.它与用于正常创建DbContext的相同.我正在尝试解决方案here

public static class SimpleInjectorInitializer
{
    /// <summary>Initialize the container and register 
    // it as MVC3 Dependency Resolver.</summary>
    public static void Initialize()
    {
        var container = new Container();            
        InitializeContainer(container);
        container.RegisterMvcControllers(
            Assembly.GetExecutingAssembly());            
        container.RegisterMvcAttributeFilterProvider();       
        container.Verify();            
        DependencyResolver.SetResolver(
            new SimpleInjectorDependencyResolver(container));
    }

    private static void InitializeContainer(
        Container container)
    {
    }
}

更新：我仍然没有解决我的问题,但它与Ninject的这个问题非常相似
