🌟Open Source Contributions

• [Polly](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+.): Contributed a feature that allows dynamically setting the breaking time of the circuit breaker. This enhancement enables developers to adjust the breaker behavior at runtime, improving resilience in various failure scenarios.
• TableCloth: Implemented a favorites feature, allowing users to bookmark frequently used configurations for easier access and improved user experience.
