LightResults - Operation Result Patterns for .NET

Star Issue Sponsor

LightResults is an extremely light and modern .NET library that provides a simple and flexible implementation of the Result Pattern. The Result Pattern is a way of representing the outcome of an operation, whether it's successful or has encountered an error, in a more explicit and structured manner. This project is heavily inspired by Michael Altmann's excellent work with FluentResults.
