This paper presents the compilation of the Scheme programming language to .NET. This platform provides a virtual machine, the Common Language Runtime (CLR), that executes bytecode, the Common Intermediate Language (CIL). Since CIL was designed with language agnosticism in mind, it provides a rich set of language constructs and functionalities. As such, the CLR is the first execution environment that offers type safety, managed memory, tail recursion support and several flavors of pointers to functions. Therefore, the CLR presents an interesting ground for functional language implementations. We discuss how to map Scheme constructs to CIL. We present performance analyses on a large set of real-life and standard Scheme benchmarks. In particular, we compare the speed of these programs when compiled to C, JVM and .NET. We show that in term of speed performance of the Mono implementation of .NET, the best implementing running on both Windows and Linux, still lags behind C and fast JVMs such as the Sun's implementations.
