## What it is
UnrealSharp is an open-source Unreal Engine 5 plugin that lets developers write game logic in C# on .NET 10, with automatically generated bindings from reflected C++ code. It supports hot reload without restarting the editor, full NuGet ecosystem access, and debugging from an IDE.

## Use cases
- write unreal engine 5 game logic in c# instead of c++
- hot reload c# code in unreal editor without restarting
- port blueprint projects to c#
- use nuget packages inside an unreal engine game
- transition from unity c# development to unreal engine
- expose c# classes and components to blueprints

## When to choose
- your team knows C# and wants to build UE5 games without deep C++ expertise
- you want fast iteration with hot reload while the editor is running
- you need access to the .NET ecosystem and NuGet packages in your game
- you want MIT-licensed tooling with no licensing cost

## When to avoid
- you need production-ready stability today - the project is not yet production ready
- you target Linux, iOS, or Android - those platforms are only planned
- your project is pure Blueprint with no C++ engineer available
- you need to access engine features not exposed to Unreal's reflection system
