c# - Autofac 在注册 Moq 实例时抛出 File Not Found 异常

Question

我创建了一个 Windows 8.1 App Store 单元测试项目，添加了 Moq 和 Autofac 并尝试注册一个 Mock<IAccountService>与Autofac。当我调用 RegisterInstance(serviceMock.Object)它 Autofac 抛出 File Not Found异常

界面是这样的:

public interface IAccountService
{
    Task<OperationResult> CreateAccount(User user, string password, string passwordConfirmation);

    Task<OperationResult<User>> Signin(string username, string password);
}

我设置了我的 Mock

// Set up our mocked repositories and services
var accountServiceMock = new Mock<IAccountService>();
accountServiceMock
    .Setup(service => service.CreateAccount(
        It.IsAny<User>(),
        It.IsAny<string>(),
        It.IsAny<string>()))
    .Returns((User user, string password, string passwordConfirmation) =>
        {
            var taskCompletion = new TaskCompletionSource<OperationResult>();
            taskCompletion.SetResult(new OperationResult(true));
            return taskCompletion.Task;
        });

accountServiceMock
    .Setup(service => service.Signin(It.IsAny<string>(), It.IsAny<string>()))
    .Returns((string username, string password) =>
        {
            var taskCompletion = new TaskCompletionSource<OperationResult<User>>();
            taskCompletion.SetResult(
                new OperationResult<User>(true, new User { Username = username }));

            return taskCompletion.Task;
        });

当我用 Autofac 注册模拟时，抛出异常

var builder = new ContainerBuilder();

// Exception thrown here.
builder.RegisterInstance(accountServiceMock.Object).As<IAccountService>();
IContainer container = builder.Build();

如果我使用这段代码并围绕它构建一个标准的非 App Store 单元测试项目，单元测试运行没有问题并且构建器注册了模拟实例。

我还想指出我可以使用 RegisterType().As();没有任何问题。我也可以使用 RegisterInstance使用一个具体的、非模拟的对象，没有任何异常(exception)。

我在 Windows 8.1 项目中缺少什么吗？

异常

[System.IO.FileNotFoundException]   
{"Could not load file or assembly 'ISymWrapper, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

我刚刚发布了另一个可能对您有帮助的问题的答案。它将为您提供一个指向替代模拟框架的链接，该框架可以轻松地与 Windows 应用商店应用程序一起使用。

我目前将它与 Unity 一起用作 DI 容器和 Prism。
