Transient Fault Handling Application Block/Retry patterns for modern .NET.

TransientFaultHandling.Core is retry library for transient error handling. It is ported from Microsoft Enterprise Library’s Transient Fault Handling Application Block, a library widely used with .NET Framework.

  • The retry pattern APIs are ported to .NET 6 & .NET 5 & .NET Core & .NET Standard.
  • New functional and fluent APIs to easily implement retry logic.
  • The outdated configuration & APIs are replaced by modern .NET JSON/XML/INI configuration.


With this library, the old code with retry logic based on Microsoft Enterprise Library can be ported to .NET 6 & .NET 5 & .NET Core & .NET Standard without modification:

ITransientErrorDetectionStrategy transientExceptionDetection = new MyDetection();
RetryStrategy retryStrategy = new FixedInterval(retryCount: 5, retryInterval: TimeSpan.FromSeconds(1));
RetryPolicy retryPolicy = new RetryPolicy(transientExceptionDetection, retryStrategy);
retryPolicy.ExecuteAction(() => webClient.DownloadString("https://DixinYan.com"));

With this library, it is extremely easy to detect transient exception and implement retry logic. For example, the following code downloads a string, if the exception thrown is transient (a WebException), it retries up to 5 times, with it waits for 1 second between each retry:

    () => webClient.DownloadString("https://DixinYan.com"),
    isTransient: exception => exception is WebException,
    retryCount: 5, retryInterval: TimeSpan.FromSeconds(1));

Fluent APIs are also provided for even better readability:

    .WithIncremental(retryCount: 5, initialInterval: TimeSpan.FromSeconds(1),
        increment: TimeSpan.FromSeconds(1))
    .Catch<WebException>(exception =>
        exception.Response is HttpWebResponse { StatusCode: HttpStatusCode.RequestTimeout })
    .ExecuteAction(() => webClient.DownloadString("https://DixinYan.com"));

It also supports JSON/XML/INI configuration:

  "retryStrategy": {
    "name1": {
      "fastFirstRetry": "true",
      "retryCount": 5,
      "retryInterval": "00:00:00.1"
    "name2": {
      "fastFirstRetry": "true",
      "retryCount": 55,
      "initialInterval": "00:00:00.2",
      "increment": "00:00:00.3"
