# Contributions to App-vNext/Polly Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. From version 6.0.1, Polly targets .NET Standard 1.1 and 2.0+. This repository holds only my commits to the upstream project, with their original author, date and diff. Each of my commits is preceded by a snapshot of the upstream files it touched, so every diff shows exactly what I changed. ## Merged pull requests - [Return null from FaultGenerator when no fault is generated](https://github.com/App-vNext/Polly/pull/3220) (2026-09-06)
