Rethought.Retry

A lightweight .Net Standard library that assists in retrying

Install from Nuget

Getting Started

Usage is quite simple. All you need is the static RetryService class.

var result = await RetryService.RetryAsync<int>(async cancellationToken =>
    {
        // Some async operation that calculates a number
        Console.WriteLine("Calculation finished!");
        return 5;
    }, 
    3,
    TimeSpan.FromMinutes(5));

// RetryAsync returns an Option<T> to avoid null
// See below how to resolve the value
if (result.TryGetValue(out var value))
{
    Console.WriteLine($"The result is {value}.");
}
else
{
    Console.WriteLine("No result available.");
}

It is also possible to pass in a CancellationToken with an overload. This CancellationToken is then being passed into the Func where your main workload occurs.

However, you don't have to use the RetryService. You can also create your own implementation of ITrier. RetryService uses the default implementation Trier.

Limitations

• The library is exclusively async. A workaround is to return Task.CompletedTask instead.
• The retry methods expect to return a result
