C# Polly, 1st SqlException retry after 10 seconds then other all retries after 5 seconds until total 3 minutes

I am implementing Polly to retry SqlConnection errors.

This is the logic I need to implement:

• 1st SqlException - retry after 10 seconds
• Total retrying time is 3 minutes
• After 1st retry, all other retry after 5 seconds

// the following should retry with 5 second delays between tries, up to a 3-minute limit:Policy timeoutAfter3Minutes = Policy.Timeout(TimeSpan.FromMinutes(3));Policy retryEveryFiveSeconds = Policy.Handle<Exception>()                               .Or<TimeoutException>()                               .Or<SqlException>()                               .WaitAndRetryForever(sleepDurationProvider: i => TimeSpan.FromSeconds(5)                               ,(exception, retry, timespan) =>                               {                               Console.WriteLine($"Retry count is {retry} and timespan is {timespan} " + $"at {DateTime.Now.ToString("hh.mm.ss.ffffff")}");                               });// 1st (1 time only): retry after 10 secPolicy retryFirstTime = Policy  .Handle<Exception>()  .Or<TimeoutException>()  .Or<DivideByZeroException>()  .WaitAndRetry(1, sleepDurationProvider: i => TimeSpan.FromSeconds(10),   (Exception exception, TimeSpan timeSpan, int retryCount, Context _) =>   {         Console.WriteLine($"1st retrying SqlConnection on attempt : {retryCount} :          {exception.InnerException} " +         $"in {timeSpan.TotalSeconds} seconds");   });// Wrap policy with Timeout Exception every 5 sec until 3 minutesPolicy tryEvery5SecondsUpTo3Minutes = timeoutAfter3Minutes.Wrap(retryEveryFiveSeconds);// Wrap policy 1st retry after 10 seconds and other retries at 5 seconds until 3 minutesPolicy combinePolicy = Policy.Wrap(retryFirstTime, tryEvery10SecondsUpTo5Minutes); // Usage     combinePolicy.Execute(() => reTryDB(conn));public static void reTryDB(SqlConnection conn){     Console.WriteLine($"Open Sql con at {DateTime.Now.ToString("hh.mm.ss.ffffff")}");     conn.Open();      string selectCommand = "SELECT TOP 1 * FROM [dbo].[TAbleA]";     var command = new SqlCommand(selectCommand, conn);     try     {         using (SqlDataReader reader = command.ExecuteReader())         {             while (reader.Read())             {                 Console.WriteLine(String.Format("{0}", reader[0]));             }         }     }     catch (Exception ex)     {         Console.WriteLine(ex.ToString());     }     conn.Close();}

Here it retries every 5 seconds. I can not able to split 1st retry at 10 seconds, and all other retry every 5 seconds until a maximum of 3 minutes.

Can someone give me idea how can I use PollyWrap to combine these 2 policies?
