cfg.UseRetry(); with the new Lambda-based retry policy configurator throw exceptions

Getting exceptions that the RetryPolicy cannot be null, after i Upgraded to MT 3.5.4.

The service bus was not properly configured: [Failure] RetryPolicy must not be null

   private static IBusControl CreateIBusControl(Container container)
        {
            var configurator = container.GetInstance<IBusConfigurator>();

            var bus = configurator
                .CreateBus((cfg, host) =>
                {
                    cfg.ReceiveEndpoint<CollectCommand>(c =>
                    {
                        c.LoadFrom(container);
                    });
                    // works
                    cfg.UseRetry(Retry.Exponential(3, TimeSpan.FromSeconds(5), TimeSpan.FromMinutes(2), TimeSpan.FromSeconds(5))); 
                    // doesn't work
                    cfg.UseRetry(r => Retry.Exponential(3, TimeSpan.FromSeconds(5), TimeSpan.FromMinutes(2), TimeSpan.FromSeconds(5))); 
                })
                .ConfigureAwait(false)
                .GetAwaiter()
                .GetResult();
            return bus;
        }

Using this configurator helper class:

        public async Task<IBusControl> CreateBus(Action<IBusFactoryConfigurator, IHost> registrationAction = null, Action<IRetryConfigurator> retryGlobalPolicy = null)
        {
            var t = await Task.Run(() =>
            {
                var connUri = new Uri(Configuration.ConnectionUri);
                var bus = Bus.Factory.CreateUsingAzureServiceBus(cfg =>
                {
                    var host = cfg.Host(connUri, hst =>
                    {
                        hst.TokenProvider = TokenProvider.CreateSharedAccessSignatureTokenProvider(Configuration.Login, Configuration.Password);
                    });

                    registrationAction?.Invoke(cfg, host);
                    cfg.UseJsonSerializer();
                });
                return bus;
            });
            return t;
        }

Ah, so simple a miss and course it works now when actually using the lambda! (using r.* not Retry.*) Much gratitude for the effort and time used to answer this issue!

Pull request submitted, short answer, you weren’t using the lambda, you were just doing essentially a no-op in the method.
