## What it is
Svelto.ECS is a C# Entity Component System framework for writing data-oriented, cache-friendly game code. It is platform-agnostic (.NET Standard 2.0+) with dedicated Unity extensions.

## Use cases
- build games with an entity component system architecture in C#
- write data-oriented cache-friendly game logic
- manage thousands of game entities efficiently in Unity
- decouple game behavior from object hierarchies
- prototype ECS patterns outside Unity with plain .NET

## When to choose
- you are developing a Unity or C# game that benefits from ECS architecture
- you want an established, actively maintained ECS framework with MIT licensing
- you need platform-agnostic ECS usable with .NET Standard 2.0+

## When to avoid
- your team is not prepared to shift from OOP to ECS thinking
- you need a full game engine rather than an architectural framework
- you target C# versions older than 7 or runtimes without .NET Standard 2.0

## Facets
- artifact type: framework
- maturity: active
- function: game-engine, simulation
- domain: programming-languages
- platform: cross-platform, game-engine, dotnet
- tags: ecs, entity-component-system, data-oriented-design, csharp, unity, game-development
