Unity应用程序块2.0-给定的程序集名称或代码基无效

namespace Interfaces
{
    public interface IDoSomeWork1
    {
        string DoSomeWork1();
    }
}

namespace Interfaces
{
    public interface IDoSomeWork2
    {
        string DoSomeWork2();
    }
}

依赖项(在名为“实体”的程序集中)。在项目中:-实体)

namespace Entities
{
    public class ClassB : IDoSomeWork1
    {
        public string DoSomeWork1()
        {
            return this.ToString();
        }
    }
}

namespace Entities
{
    public class ClassC : IDoSomeWork2
    {
        public string DoSomeWork2()
        {
            return this.ToString();
        }
    }
}

类(在项目中:-UsingUnity)

public class ClassA
    {
        [Dependency]
        public IDoSomeWork1 DoSomeWork1 { get; set; }
        [Dependency]
        public IDoSomeWork2 DoSomeWork2 { get; set; }


        public void SomeMethodInClassA()
        {
            Console.WriteLine(DoSomeWork1.DoSomeWork1());
            Console.WriteLine(DoSomeWork2.DoSomeWork2());
        }
    }

App.Config(在控制台应用程序项目中:-ConsoleUsingUnity)

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="unity"
                 type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,
                   Microsoft.Practices.Unity.Configuration" />
    </configSections>
    <unity>
        <containers>
            <container>
                <types>
                    <type type="Interfaces.IDoSomeWork1, Interfaces"
                          mapTo="Entities.ClassB, Entities" />
                    <type type="Interfaces.IDoSomeWork2, Interfaces"
                          mapTo="Entities.ClassC, Entities" />
                </types>
            </container>
        </containers>
    </unity>
</configuration>

public class Class1
    {
        static void Main(string[] args)
        {
            IUnityContainer container = new UnityContainer();

            // Load from config file
            UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity");
            section.Configure(container);

            ClassA classA = container.Resolve<ClassA>();
            classA.SomeMethodInClassA();
        }
    }

当我运行客户机时,在section.Configure(container);,出现以下错误:-

是无效的。(HRESULT的异常: 0x80131047)

我不确定配置或类型是否有问题。有人能指出这里的错误吗?
