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
