}
}
public class Program
{
public async Task Main(string[] args)
{
var builder = new ContainerBuilder();
// this will add all your Request- and Notificationhandler
// that are located in the same project as your program-class
builder.RegisterMediatR(typeof(Program).Assembly);
var container = builder.Build();
var mediator = container.Resolve<IMediator>();
var response = await mediator.Send(new PingCommand());
