Very nice! I have a "scratchpad" project for fiddling around with things, but this might wind up a permanent tab on my browser. Less overhead than a VS project, for sure.
After using F# and having F# Interactive onhand, I cannot imagine working without a REPL. There's so many small things that become simple to check if you've got a REPL handy.
What kind of hardware are you using? Are the jobs parallel? I do not know about .NET very much, but it seems very slow. Would that be feasbile for you to maintain this?
http://liveweave.com is by far the best HTML/CSS/JS playground out there. you guys should totally try it out.
Honest question: Why?
I think I can answer that. IMHO Liveweave has something most of the other JS "playgrounds" do not have. It has context-sensitive code-hinting for core JavaScript and jQuery...also for CSS/HTML/HTML5/CSS3. Personally, I think this makes a huge difference, at least for me and may be some others.
Boohoo, any file access is disabled, and any Environment.GetFolderPath will return an empty string (except System, which throws a security violation) :P
We may look to add local storage sandbox for this.
This is great. One small bug cropped up, I collaborated on a fiddle with a work colleague and he couldn't see any output from clicking Run. http://www.dotnetfiddle.net/lN6m0S Great work though, will be in my favourites :)
Those are some curious methods, but I'm not sure the names fold and foldback are appropriate given what they actually do.
This is super awesome! I was thinking of building something like this the other day because I wanted to test some code and not make a new test console app. Totally awesome!
As stated elsewhere linqpad is really great for testing ad-hoc, throwaway C# code (much more than just linq expressions). It kind of like a REPL for .net.
If you're doing any Entity Framework development, you should be using LinqPad and checking generated SQL for pretty much every canned (read re-used, not inline) query you write. Somethings can be unexpectedly ugly and badly performing if not optimized properly.
