Send common command (query) object and get object response

Pleace add such functionality:

object query  = Activator.CreateInstance(requestType);
object response = Mediator.Send(query);
if(response is SomeType resp) 
{
 //...
}

the extension in the PR works nice though

public static class MediatorExtensions { public static async Task<object> Send(this IMediator mediator, object request, CancellationToken cancellationToken = default) { return await mediator.Send((dynamic)request, cancellationToken); } }

I have been doing this for years in one of our (plugin extendable) webservices.

• Have a registry of command names + .NET types. (plugins can register new command names + their type)
• on http request of a command, lookup it’s .NET type by command name
• use JSON deserializer to deserialize to that type
• because it’s all runtime, you get back an ‘object’ from the serializer,
• using that MediatR extension I send the command (object) to mediatr

Works like a charm
