如何通过约定将通用接口绑定到Ninject中的多个通用具体类型

Question

I have a multiple object that implements the same generic interface. So, I want to configure it using Ninject conventions but I don't know how to do it.

Right now I have these registrations

Bind<IQueryHandler<GetPagedPostsQuery, PagedResult<Post>>>().To<GetPagedPostsQueryHandler>();
Bind<IQueryHandler<GetPostByDateQuery, Post>>().To<GetPostByDateQueryHandler>();

I tried this convention

Kernel.Bind(x => x
  .FromThisAssembly()
  .IncludingNonePublicTypes()
  .SelectAllClasses()
  .InheritedFrom(typeof(IQueryHandler<,>))
  .BindDefaultInterface());

But doesn't register any query handler.

Is posible to do it with conventions?

** Edit ** The classes are the followings

public class GetPagedPostsQueryHandler : IQueryHandler<GetPagedPostsQuery, PagedResult<Post>>
public class GetPostByDateQueryHandler : IQueryHandler<GetPostByDateQuery, Post>

BindDefaultInterface means that MyService : IMyService, IWhatever will be bound to IMyService .

You should use BindSingleInterface , which worked instantly when I tried it in a Unit Test:

[TestMethod]
public void TestMethod2()
{
    var kernel = new StandardKernel();

    kernel.Bind(c => c.FromThisAssembly()
                        .IncludingNonePublicTypes()
                        .SelectAllClasses()
                        .InheritedFrom(typeof(IQueryHandler<,>))
                        .BindSingleInterface());

    kernel.TryGet<IQueryHandler<GetPagedPostsQuery,PagedResult<Post>>>()
        .Should()
        .NotBeNull();
}
