Hi lovely people 😄 👍🏼
Microsoft develops a special kernel for Jupyter Notebooks that can interact with different languages.
That way, you can **share variables** between F#, R, Javascript, Python [and others.](https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.dotnet-interactive-vscode)
It seems almost trivial, to implement new languages, you simply connect to an existing kernel.
The whole things acts as a single kernel, that can have multiple [subkernel](https://github.com/dotnet/interactive/blob/main/docs/FAQ.md#what-is-a-subkernel)
The nice thing about that is, that its compatible with all existing Jupyter implementations,
so JupyterLab, VSCode, IDEA, nteract and so on. 🙂
I could open up an issue on Github.
As someone, who is not into data science (as this seems mostly useful for), I like to ask first, if that is actually useful, or if the current Julia Jupyter kernel can do all of that for you as is.
**Is this useful to you?**

[It seems like this is working already.](https://github.com/dotnet/interactive/issues/3209#issuecomment-1743345972)
I will try this tomorrow 🙂

Looks interesting. Does it work on other OS besides Windows? Apparently, it needs the .NET SDK

I love that people are still under the impression, that .NET is Windows exclusive.
They seem to have missed clearing up this situation.
As someone coming from the ecosystem: .NET is fully cross-platform.
They have done a pretty good job in this regard.
The current implementation is actually done from scratch, fully cross-platform.
And the old .NET, that was Windows exclusive, is canceled, and only seen as legacy platform.
They did an entire rewrite, and that was initially called **.Net Core**.
And they then ultimately renamed it.
Back to .NET. 😄
And now, you get .NET on Linux and macOS natively. 😉
