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?
no, not at the moment
I would greatly appreciate this feature as well.
Yeah me too!
