FusionC#
Fusion Framework for C# via fusion-ffi
Overview
C# bindings call the Rust core through fusion-ffi (C ABI). DX mirrors Python/Node: FusionApp, [Route], middleware, Status, and settings.
v1 focuses on a runnable HTTP API. Full OpenAPI/Swagger parity with Python is not included yet.
Managed package: NuGet Fusion-Framework (C# namespace FusionFramework). Native library comes from fusion-ffi (bundled with the NuGet package for published builds).
