Making HTTP calls is one of the most fundamental operations in modern application development. Whether you’re consuming REST APIs, downloading files, or communicating with microservices, your choice of HTTP client library has a direct impact on your code’s readability, maintainability, and performance. In the .NET ecosystem, three options stand out: RestSharp, Refit, and the built-in HttpClientFactory. Each takes a fundamentally different approach to HTTP communication, and choosing the wrong one can lead to verbose, error-prone code — or worse, socket exhaustion under load.
