It translates MSIL to Javascript, including re-bindings enough of the libraries including XNA to work. In the same vein that emscriptem does for LLVM bitcode, but with less of an impedance mismatch.

I gather it is quite a smart translator, too. It understands the classes and type of MSIL to generate the most idiomatic code, and recognizes control flow, so it is not just an unrolled interpreter.

Personally I'm fascinated. Looks like a lot more pleasant way of producing HTML5 games, (even though I kinda like javascript).

Do you know how it compares to GWT (https://code.google.com/webtoolkit/)?
(GWT does Java to JavaScript compilation)

Well the guy making it has a focus on games.

You mean that it will be limited in that it will only be for games? Or that it will do games better because it is specialized?

I'm not the spokesperson here. I just meant that he chose a game for his first demo, and ported at least some of XNA.

I find it very impressive and am asking questions because I want to know more. But if you don't know the answers, that's totally fine too.

My first demo was actually a toy C# raytracer somebody wrote, since all I needed to get that up and running was to implement a few System.Drawing.Bitmap methods atop canvas. This is the fourth demo I've ported, and it's the first one that ran well and was still a 'real' application (scare quotes because really, it's just a tutorial).

It's not focused on games, but my personal focus is games, since that's what I want to run in the browser. It's certainly designed to work for regular applications/libraries just as well as it does for games.

Conceptually it is similar to GWT, but there are lots of philosophical differences - GWT is basically designed to generate obfuscated, 'read-only' JS code, and the result either works or it doesn't. JSIL attempts to produce readable, debuggable JS that corresponds as closely to the original author's intent as possible, so that getting things up and running is straightforward and people running your app in the browser aren't forced to live as second-class citizens.

Woah, Kaelan, really great stuff!

I stumbled upon this today and was pretty impressed. I've always thought about doing something like this but I fear my js skills aren't up to the task.

Amaizing! I can;t wait for the time we'll be able to write html 5 games in C#  :tearsofjoy:

Hey,

SharpKit converts direct C# source files into JavaScript, and also have CLR support.

Even though this does translate C# to Javascript - I do see it more as a XNA to HTML5 translator.

But this very impressive. We have once used Silversprite (XNA to Silverlight), but this actually seems to work better - it's way more smooth.

If anyone here has a game built with XNA (or just C#) that you'd like to port to JavaScript, drop me a note. I'd be glad to help you get up and running, and identify any problems in JSIL I can fix to make your stuff work.
