Microsoft Transient Fault Handling Application Block ("Topaz") - October 2012 Update

Release Notes


What's New

  • The ExecuteAsync method now retries if an exception is thrown synchronously and is transient when starting the user provided task.
    • In the previous release, synchronous errors were not retried, following TAP design guidelines that dictate that a task should fail to start only if there is a usage error (and hence not transient), but there are cases where these guidelines may not be followed by libraries or user code and Topaz cannot enforce those.
    • If the exception is not transient, Topaz will still bubble up the exception synchronously (as opposed to returning a task with a Faulted state).
  • Improved Windows Azure Service Bus detection strategy to better support transient errors when authenticating with Windows Azure Access Control Service (ACS).

Usage and behavior
