Transcript

Retry operations should only be attempted when the faults are transient. If there isn't some decent likelihood that the retry operation will be successful, it shouldn't even be attempted. It makes no sense to reattempt an operation when there is no chance of it completing successfully. Generally speaking, retries should only be implemented when the full impact can be determined. Additionally, conditions should be well-understood and validated. Keep in mind that the errors that are returned from services outside of your control often evolve over a period of time. This will require you to reevaluate the transient fault detection logic that you've deployed. 

When creating components and services you should consider including error codes and help messages that will assist clients in determining whether they could retry failed operations. More specifically, you should indicate if the client should retry the operation and then suggest a valid delay before the next retry attempt. When building a web service, it's best to consider including custom errors that are defined within service contracts. Although generic clients may not be able to read them, they'll be useful when building custom clients.
