یک پروژه NET Core MVC Web Api ایجاد کردم و از Dependency injection , Repository pattern استفاده کردم برای inject کردن repository به کنترلر ولی خطای زیر رو میگیرم

نمونه کد هایی که استفاده کردم :
Startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
services.AddScoped<IUnitOfWork, DatabaseContext>();
//....
}
public IServiceProvider ConfigureIoC(IServiceCollection services)
{
var container = new Container();
container.Configure(config =>
{
config.AddRegistry(new DefaultRegistry());
config.Populate(services);
});
return container.GetInstance<IServiceProvider>();
}
Class DefaultRegistry
public DefaultRegistry()
{
For<ICategoryRepository>().LifecycleIs(Lifecycles. Container).Use<CategoryRepository>();
For<IUnitOfWork>().LifecycleIs(Lifecycles.Containe r).Use<DatabaseContext>();
}
CategoryRepository
public interface ICategoryRepository : IGenericRepository<Category>
{
List<Category> GetAll();
Category Insert(Category model);
}
public class CategoryRepository : GenericRepository<Category>, ICategoryRepository
{
IUnitOfWork _uow;
Lazy<DbSet<Category>> _categories;
public CategoryRepository(IUnitOfWork uow) : base(uow)
{
_uow = uow;
_categories = new Lazy<DbSet<Category>>(() => _uow.Set<Category>());
}
//....
}
BaseApiController
public class BaseApiController : Controller
{
public IUnitOfWork _uow { get; set; }
public BaseApiController(IUnitOfWork uow)
{
_uow = uow;
}
}
CategoryController
public class CategoryController : BaseApiController
{
Lazy<ICategoryRepository> _categoryRepository;
public CategoryController(IUnitOfWork uow, Lazy<ICategoryRepository> CategoryRepository) : base(uow)
{
_categoryRepository = CategoryRepository;
}
[HttpGet, Route("getall")]
public ActionResult GetGategories()
{
List<Category> lst = _categoryRepository.Value.GetAll();
GetCategoriesResponse Response = new GetCategoriesResponse();
Response.Categories = lst;
Response.Result = ResponseEnum.OK;
return Ok(Response);
}
}
