Feature Request: C# REPL

[martinsuchan]

One feature I really miss in Visual Studio Code right now is the C# Interactive/REPL. It was added to full Visual Studio in late 2015 and it's highly useful for testing code snippets.

If this functionality is already provided by this addon, then I was not able to find it.

This could be integrated via the VS Code Terminal API. For example Ionide has a nice FSI integration.

It would be great if the C# extension bundled CSI.

Here is the Ionide experience

Would love that

VS Code is nice for testing something small out. Would love to see something like what you get with LinqPad with a visualizer for many datatypes as well.

With Ionide-fsharp, F# Interactive in Visual Studio Code is brilliant:

• FSI: Start
• FSI: Send File
• FSI: Send Line
• FSI: Send Selection
• FSI: Send References from project

It would be great to have similar commands for C# Interactive

Is this still not a thing?

[filipw]

no, not at the moment

I would greatly appreciate this feature as well.

I love and use REPLs all the time (coming from Python) and would love to see this too. However, in the meantime, check out CSharpRepl which you can easily use in any terminal with completions and syntax highlighting. It's very good!

Hope this helps

@fgimian I've been looking for even a half-decent REPL for ages, without success. The one you posted is simply incredible. Thank you!

fsi ships in the .NET SDK and I think similarly csi should ship too. Then the repl would be available for everyone not just VSCode users and could be opened in the terminal.
