Building a Resilient .NET Web API
In modern distributed systems, failure is not an exception, it is an expectation. When your API depends on external services, HTTP calls can fail due to many reasons such as network issues, timeouts, service overload, temporary outages, etc. The real challenge is not avoiding these failures, but handling them gracefully.
Starting with .NET 8, Microsoft introduced the Microsoft.Extensions.Http.Resilience package, which provides built-in resilience strategies for HttpClient, powered by Polly. This makes it easier than ever to implement patterns like retries, circuit breakers, timeouts, and more.
In this series, you’ll learn how to build resilient APIs by applying these patterns in real-world scenarios.
Below, you’ll find all articles in the series, along with the GitHub repository containing the full source code.
