Marc Rocny enhanced the Polly retry strategy example in the App-vNext/Polly repository, focusing on improving code clarity and reliability for developers adopting retry patterns. He refactored C# example snippets to resolve null-reference warnings and addressed IDE suggestions, ensuring the sample code adhered to modern coding standards. By correcting the ShouldHandle logic, Marc enabled accurate exception detection within the retry strategy, aligning the example with intended behavior. His work emphasized code refactoring and example code improvement, resulting in more maintainable documentation. These changes streamlined developer onboarding and reduced confusion, ultimately supporting both users and maintainers in understanding Polly’s retry mechanisms.
