Support for generic notifications?

[AnderssonPeter]

Hi are there any plans to add support for generic notifications?

I have the following:

public record PostCommandHandledNotification<TCommand>(TCommand Command) : INotification where TCommand : notnull, IMessage;

public class PostCommandBehavior<TMessage, TResponse>(IMediator mediator, ILogger<PostCommandBehavior<TMessage, TResponse>> logger) : IPipelineBehavior<TMessage, TResponse> where TMessage : notnull, IMessage
{
    public async ValueTask<TResponse> Handle(TMessage message, MessageHandlerDelegate<TMessage, TResponse> next, CancellationToken cancellationToken)
    {
        var result = await next(message, cancellationToken);
        string typeName = message.GetType()?.FullName ?? message.GetType().ToString();
        bool isCommand = typeName.EndsWith(MediatorConstants.CommandSuffix);
        if (isCommand)
        {
            await mediator.Send(new PostCommandHandledNotification<TMessage>(message), CancellationToken.None);
        }
        return result;
    }
}

public class PostEditStorageCommandHandler(IWorkItemManager workItemManager, IUnitOfWork unitOfWork) : INotificationHandler<PostCommandHandledNotification<EditStorageCommand>>
{
    public async ValueTask Handle(PostCommandHandledNotification<EditStorageCommand> notification, CancellationToken cancellationToken)
    {
        ....
    }
}

Sadly this generates invalid code:

public readonly global::....API.Mediator.Internals.NotificationHandlerWrapper<global::....Core.PostCommandHandledNotification<TCommand>> Wrapper_For_..._Core_PostCommandHandledNotification;

public global::System.Threading.Tasks.ValueTask Publish(
    global::....Core.PostCommandHandledNotification<TCommand> notification,
    global::System.Threading.CancellationToken cancellationToken = default

Both of those lines generate the error The type or namespace TCommand could not be found.

Thanks for your response, I managed to work around the problem by having my generic class being a base class, that I inherit and then use reflection to send the correct type instead, this seems to work but requires more manual work than a Generic notification, but it's better than nothing!
