具有接口的Ninject和repository模式

这是我现在拥有的接口/类结构:

BaseContentObject抽象类

public abstract class BaseContentObject : IEquatable<BaseContentObject>
{
...
}

页面具体类

public class Page : BaseContentObject
{
...
}

public interface IContentRepository<T>
    {
        // common methods for all content types
        void Insert(T o);
        void Update(T o);
        void Delete(string slug);
        void Delete(ContentType contentType, string slug);
        IEnumerable<T> GetInstances();
        T GetInstance(ContentType contentType, string slug);
        T GetInstance(string contentType, string slug);
        T GetInstance(string slug);
        IEnumerable<string> GetSlugsForContentType(int limit = 0, string query = "");
        ContentList GetContentItems();
        bool IsUniqueSlug(string slug);
        string ObjectPersistanceFolder { get; set; }
    }

公共接口实现(对于继承BaseContentObject类的所有内容类)

    public class XmlRepository<T> : IContentRepository<BaseContentObject>
    {
        public string ObjectPersistanceFolder { get; set; }

        public XmlRepository()
        {
            ObjectPersistanceFolder = Path.Combine(XmlProvider.DataStorePhysicalPath, typeof(T).Name);
            if (!Directory.Exists(ObjectPersistanceFolder))
                Directory.CreateDirectory(ObjectPersistanceFolder);
        }
...
}

特定于内容的存储库

public class XmlPagesRepository : XmlRepository<Page> { }

global.asax.cs中的Ninject规则

Bind<IContentRepository<Page>>().To<XmlPagesRepository>();

这将产生以下编译时错误:

*The type 'Namespace.XmlPagesRepository' cannot be used as type parameter 'TImplementation' in the generic type or method 'Ninject.Syntax.IBindingToSyntax<T>.To<TImplementation>()'. There is no implicit reference conversion from 'Namespace.XmlPagesRepository' to 'Namespace.IContentRepository<Namespace.Page>'.*

我想在ASP.NET MVC控制器中使用以下结构:

    public IContentRepository<Page> ContentRepository { get; private set; }

    public PageController(IContentRepository<Page> repository)
    {
        ContentRepository = repository;
    }
