> But do we really have to compile C# to IL bytecode to CPP source to LLVM IR to asm.js javascript which the browser will compile to native code. I guess you're saying that it sounds like a convoluted process? There are other ways to run C# on the web, like JSIL which compiles C# more directly to JS. In practice each approach has benefits and disadvantages. But I wouldn't say that C# to IL to C++ to LLVM to asm.js to native is convoluted. It reuses a lot of existing tools (LLVM, Emscripten), and makes a lot of sense: Once you have C# to C++, you can compile that on any C++ compiler, including platforms where you couldn't run the Mono VM. C++ is as portable as it gets.
