Marc Rocny enhanced the reliability and clarity of retry strategy examples in the App-vNext/Polly repository by addressing a bug in the ShouldHandle logic, ensuring exceptions are correctly detected during retries. He refactored C# example code to resolve null-reference warnings and incorporated IDE suggestions, aligning the samples with established coding standards. Through focused code refactoring and example code improvement, Marc improved the accuracy and maintainability of the documentation, making it easier for developers to understand and adopt Polly’s retry patterns. His work reduced confusion for users and maintainers, supporting faster onboarding and decreasing support queries related to example behavior.
