Show HN: C# Pad – Interactive C# REPL

[sandyarmstrong]

This isn't really a REPL, though. It's missing the L. :-) Not evaluating each line as it comes makes it less fun to use.

With some obvious caveats, I'm a big fan of the csharp REPL provided by Mono: http://www.mono-project.com/CsharpRepl

Yeah, that will be too costly because it would have to make a server call pretty quickly to confirm that the code is complete. (The Roslyn desktop C# Interactive can do this because it's right on the desktop)

You can press Ctrl-Enter to send complete code, if you wish to send submissions faster.

Not quite REPL (not sure C# is a great fit for REPL) but I've found LINQPad very useful for trying out code snippets locally. https://www.linqpad.net

[usea]

LINQPad is one of the best tools I've ever used. I can't recommend it enough for anybody who wants a C# or F# scratchpad, or wants to quickly query a database.

I've written a blog post on Getting Started at http://www.ahuwanya.net/blog/post/introducing-csharp-pad

Wow, I was just looking for this a couple of days back!

[ScottWhigham]

Seems interesting but I got a 'Server Error: timeout' when trying to run a simple string.Format(). Bookmarked to try later!

[sunnya]

There's a lot of Traffic on the server at the moment. Do try again later.

Seeing the same for a Hello World.

[lukasm]

compile roslyn to js. Don't really need server here do you?

[sunnya]

I didn't know that was possible. Even if you can compile Roslyn to JS to run on the client, you still need to compile most parts of the BCL as well, or else you still need to make a server call.

Is this using ScriptCS?

[sunnya]

No, it's using Roslyn directly.

[polskibus]

Immediate window?

[sunnya]

It's the web version of the Interactive window bundled with Roslyn.
