## What it is
A Promises/A+ compliant promises library for C# for managing asynchronous operations, inspired by JavaScript promises. It is widely used for game development on Unity3d and is available as the RSG.Promise NuGet package.

## Use cases
- manage asynchronous operations in C# with promises
- chain async operations in Unity3d games
- avoid callback hell in C# async code
- combine multiple async operations with Promise.All
- report progress of long-running async tasks in Unity
- handle async errors with catch and finally in C#

## When to choose
- you are building games or simulations in Unity3d and want JavaScript-style promises
- you need a Promises/A+ compliant async workflow library for C#
- you want promise chaining, progress reporting, and Promise.All combinators in .NET

## When to avoid
- you are on modern .NET and prefer built-in async/await with Task and TaskCompletionSource
- you need a library with frequent updates and active maintenance
- you need cancellation-first async patterns rather than promise semantics

## Facets
- artifact type: library
- maturity: maintenance
- function: concurrency, developer-tools
- domain: developer-tools, cross-platform
- platform: cross-platform, game-engine, dotnet
- tags: promises, async, csharp, unity3d, promises-a-plus, promise-chaining, game-development
