Question

是的，我尝试使用Stackoverflow问题/答案中的其他建议进行修复。

奇怪的是，我以为我已经修好了......
我读过关于web api和mvc解析器与ninject的不同之处，所以我认为我在一周前修好了。
在删除现有软件包之后，我最终得到了nuget的所有软件包，所以也许Nuget搞砸了什么？

这是我的错误

Ninject的一部分

private static void RegisterServices(IKernel kernel)
{
   kernel.Load(Assembly.GetExecutingAssembly());
}

web api控制器

public class AssignmentController : ApiController
{
    private readonly IUnitOfWork _UnitOfWork;

    public AssignmentController(IUnitOfWork unitOfWork)
    {
        _UnitOfWork = unitOfWork;
    }

    public List<Assignment> GetAssignments()
    {
        var result = _UnitOfWork.AssignmentsRepository.Get();
        return result;
    }

    //......
  }
