Possible to use generic handler?

[sgashua]

To prevent too much works to do from creating too many handlers classes, is it possible to use generic handler for all entities? Or not recommended to use generic handler?

From

public partial class CreateBrandCommand : IRequest<Result<int>>
    {
        public string Name { get; set; }
        public string Description { get; set; }
        public decimal Tax { get; set; }
    }
public class CreateBrandCommandHandler : IRequestHandler<CreateBrandCommand, Result<int>>
    {
        private readonly IBrandRepository _brandRepository;
        private readonly IMapper _mapper;
...

To this generic handler

public partial class CreateCommand<T> : T, IRequest<Result<int>> where T : class { } 
public class CreateCommandHandler : IRequestHandler<CreateCommand<T>, Result<int>>
{
      private readonly IBaseRepository<T> _repo;
...

But I cannot get generic handler working. How to get it working?
