An experimental Rust compiler backend plugin that transpiles Rust code into .NET CIL assemblies or C source files. It includes a Rust/.NET interop layer for calling .NET APIs from Rust and exposing Rust code to .NET languages like C# and F#.

Use cases

• compile Rust code to run on .NET runtime
• use Rust libraries from C# or F# projects
• transpile Rust to C source code
• call .NET APIs like StringBuilder from Rust
• run Rust on platforms without native Rust toolchains
• define .NET classes implemented in Rust

When to choose

• you want to integrate Rust code into an existing .NET codebase
• you need to compile Rust to C for a platform without LLVM support
• you want to experiment with alternative Rust compiler backends

When to avoid

• you need production-grade reliability - the project warns against serious use
• you rely on procedural macros, which are not yet supported
• you need fully functional Rust std - it is only ~95% working on .NET and ~80% on C
