Show HN: Write native binary web apps with TypeScript and Express (github.com)

Interesting project! Added it to my list of TypeScript derived languages: https://github.com/orta/awesome-typescript-derived-languages

Anyone know why the parent project, Tsonic, would compile Typescript to C# instead of directly to CIL? Is it because there's a closer 1:1 mapping between the language primitives or some other reason?
