## What it is
bflat is a C# compiler and ahead-of-time runtime that combines Roslyn and NativeAOT to produce small, self-contained native executables without needing the dotnet SDK, MSBuild, or NuGet. It supports cross-compilation to Linux, Windows, Android (bionic), and UEFI targets, and can emit native shared libraries for FFI.

## Use cases
- compile C# to a small self-contained native executable
- cross-compile C# programs for Windows and Linux from one machine
- build C# apps without installing the dotnet SDK
- compile C# to a shared library callable via FFI
- build minimal C# binaries for UEFI
- run C# on Android with a bionic target

## When to choose
- you want Go-like simplicity for building C# tools with no SDK or NuGet dependencies
- you need small, self-contained native binaries from C# code
- you want cross-compilation targets like UEFI or Android bionic

## When to avoid
- you need the full .NET ecosystem, NuGet packages, or MSBuild project files
- you need musl-based Linux targets, which are not yet supported
- you rely on libraries or frameworks requiring the full .NET runtime
