Polly 🕊

Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. ♻️


Installing via NuGet 🗃 :

Install-Package Polly

Usage :

public class Mailer
    {
        public static bool SendEmail()
        {
            Console.WriteLine("Sending Mail ...");

            // simulate error
            Random rnd = new Random();
            var rndNumber = rnd.Next(1, 10);
            if (rndNumber != 3)
                throw new SmtpFailedRecipientException();

            Console.WriteLine("Mail Sent successfully");
            return true;
        }
    }

We retry to send the email 3 times if something failed ❌ :

var policy = Policy.Handle<SmtpFailedRecipientException>().Retry(3);
policy.Execute(Mailer.SendEmail);
