orleans-result-pattern

What problem does it solve?

The Orleans Result Pattern solves the challenge of signaling grain-method failures without exceptions, using a version-tolerant enum-based error model that serializes cleanly across grain boundaries.

Core Features & Use Cases

• Provides Result and Result<T> wrappers with an enum ErrorNr and string error messages for predictable, exception-free failure flows.
• Enables easy integration with ASP.NET Core minimal APIs and MVC endpoints on top of Orleans grains.
• Supports RFC7807-compatible validation and error reporting when ErrorNr is annotated with a ValidationError flag.

Quick Start

Define a grain contract that returns Result<string> and a client that handles success and error branches using a switch expression.
