解决ASP.NET核心中的依赖注入问题

我有三个Repository类，它们是：

1. ITechniqueRepository 
 2. ITechniqueItemRepository
 3. ITechniqueAssesstmentRepository

还有另一个Service类，它是：

ITechniqueService

在ITechniqueService构造函数中，我有以下代码来解析依赖注入 .

private readonly ITechniqueRepository _techniqueRepository;
private readonly ITechniqueItemRepository _techniqueItemRepository;
private readonly ITechniqueAssesstmentRepository _techniqueAssesstmentRepository;

    public TechniqueService(            
        ITechniqueRepository techniqueRepository,
        ITechniqueItemRepository techniqueItemRepository,
        ITechniqueAssesstmentRepository techniqueAssesstmentRepository
      ) : base(unitOfWork, settings, logger)
    {
        _techniqueRepository = techniqueRepository;
        _techniqueItemRepository = techniqueItemRepository;
        _techniqueAssesstmentRepository = techniqueAssesstmentRepository;
    }

在我的控制器构造函数中，我有以下代码来解决依赖关系 .

private readonly ITechniqueService _techniqueService;
    public TechniqueController(
        ITechniqueService techniqueService
        )
    {
        _techniqueService = techniqueService;
    }

在我的Startup类中，我有以下代码：

services.AddScoped<ITechniqueRepository, TechniqueRepository>();
services.AddScoped<ITechniqueItemRepository, TechniqueItemRepository>();
services.AddScoped<ITechniqueAssessmentRepository, TechniqueAssessmentRepository>();
services.AddScoped<ITechniqueService, TechniqueService>();

问题是当我执行我的服务时，我得到以下异常作为响应结果 .

{“StatusCode”：3，“Message”：“尝试激活'Services.TechniqueService'时无法解析类型'Data.Repositories.ITechniqueAssesstmentRepository'的服务 . ”，“MessageDetail”：“在Microsoft.Extensions.DependencyInjection .

我在哪里弄错了？
