@taomylife521 . The three reactive Policy types propagate handled exceptions out of the Policy as follows:

• Retry policies: rethrow the final exception on to your code, if all tries have failed.
• CircuitBreaker policies rethrow all exceptions, even handled ones. A circuit-breaker measures the exceptions and decides whether to introduce fail-fast breaking (break the circuit), but rethrows all exceptions.
• Fallback policies do not by default rethrow handled exceptions.

The wiki pages linked above for each Policy give more information.

For the cases when a policy rethrows an exception, you can either:

• handle it with your own try / catch; or
• use .ExecuteAndCapture(...) to capture the result of execution into a PolicyResult, and so avoid an extra try / catch.

I'm not sure if this answers your question. Let us know if you need anything else?
