我已经搜索了互联网和堆栈溢出,但根本无法解决为什么我的AutoFac断然拒绝向任何控制器注入任何东西。我的代码如下 - 所有内容都有序,但我收到以下消息:

  

尝试创建类型的控制器时发生错误   'SimpleController'。确保控制器具有无参数   公共建设者。

            // Enable the application to use a cookie to store information for the signed in user

SimpleController.cs

        public string TestInjection()
        {
            return (_testObject == null).ToString();

AccountController.cs(代码段)

[Authorize]
[RoutePrefix("api/Account")]
public class AccountController : ApiController
{
    private const string LocalLoginProvider = "Local";
    private ApplicationUserManager _userManager;
    private readonly ITestObject _testObject;

    public AccountController(ApplicationUserManager userManager,
        ISecureDataFormat<AuthenticationTicket> accessTokenFormat,
        ITestObject testObject)
    {
        UserManager = userManager;
        AccessTokenFormat = accessTokenFormat;
        _testObject = testObject;

    [AllowAnonymous]
    [HttpGet]
    public string TestInjection()
