What does Polly actually do for REST APIs?

Polly adds retry, circuit breaker, and bulkhead patterns to HTTP calls, handling transients without crashing your app.

Is Polly necessary for every .NET project?

No—if no cloud or externals, maybe skip. But most modern stacks? Absolutely.

NuGet install, wrap HttpClient with Policy, config retries. Test with chaos.

Think your REST APIs are bulletproof? One network hiccup says otherwise. Polly's here to save the day—or at least your sanity.
