The Mono team is proud to bring you a preview of C# 5.0 a few years before our friends in Building 41 do.A snapshot of the code is available in the demo-repl.zip file. This contains the csharp.exe C# REPL shell and the Mono.CSharp.dll compiler-as-a-service assembly. With Today's code drop all those scenarios now work: * Run Mono's C# compiler on .NET
* Embed Mono's Evaluator in your C# app.
* Use Mono's REPL with the .NET framework runtime. BackgroundAlthough we have had a compiler-as-a-service framework since September of 2008 it has been so far limited to Mono users, which effectively means only Linux and OSX users could use our C# REPL and the compiler as a service. The reason is that the Mono's C# compiler uses System.Reflection.Emit as its code generation backend. This API was fine for implementing C# 1.0 but required a few changes to support compiling its own core library (mscorlib, the equivalent of libc in C or rt in Java). When we started to work on our C# 2.0 support, we were working on our compiler as the language was being standardized at ECMA. Our compiler evolved faster than the underlying support for Reflection and Reflection.Emit did and this lead to more Mono-specific extensions being added to our Reflection and Reflection.Emit code. The more extensions that we depended on, the fewer chances we had of running with Microsoft's runtime. Read more: Miguel de Icaza's web log
