What is Polly NuGet package used for?

Polly adds resilience to .NET apps—retries, circuit breakers, bulkheads for flaky APIs and networks.

Is Polly necessary for all REST APIs?

No, skip for tiny internal apps; essential for cloud, external deps, or high-stakes like finance.

How do you implement Polly circuit breaker?

Use Policy.HandleResult (r => !r.IsSuccessStatusCode()).CircuitBreakerAsync(2 failures, 30s duration)—fails fast, recovers smart.
