Ninject can't create object. Exception thrown when getting from kernel

Question

When I try to create a new IRepository<Tag> using kernel.Get, Ninject throws an exception. Am I using Ninject in the correct manner and are the bindings set up correctly?

Method of class NinjectDependencyResolver:

private void AddBindings()
        {
            var mapperConfiguration = new MapperConfiguration(cfg =>
            {
                cfg.AddProfile(new TagProfile());
            });
            var mapper = mapperConfiguration.CreateMapper();
            _kernel.Bind<BlogDbContext>().ToSelf().InRequestScope();
            _kernel.Bind<IRepository<Tag>, Repository<Tag>>();
            _kernel.Bind<IMapper>().ToConstant(mapper);

            var repository = _kernel.Get<IRepository<Tag>>(); // exception thrown here
            _kernel.Bind<ITagService, TagService>();
        }

Class Repository:

`public class Repository<T> : IRepository<T> where T : class
{
    private readonly BlogDbContext _db;

    public Repository(BlogDbContext db)
    {
        _db = db;
    }
}`

P.S.. I do not know whether this is important, but its interface repository is located in the same assembly, and Ninject registration in another.

Answer 1

Your binding syntax is incorrect. Change:

_kernel.Bind<IRepository<Tag>, Repository<Tag>>();

To:

_kernel.Bind<IRepository<Tag>>.To<Repository<Tag>>();
