We are pleased to announce the December 2022 improvements to Polyglot Notebooks for Visual Studio Code. Make sure to install the Polyglot Notebooks extension from the VS Code Marketplace, or install it directly from the extension gallery in Visual Studio Code. If you haven’t read about our latest announcement regarding the difference between .NET Interactive and Polyglot Notebooks, we recommend you read this first.

Upgrade to .NET 7

Polyglot Notebooks has recently upgraded to depend on .NET 7. The extension now requires the .NET 7 SDK to work so update today! To learn more about .NET 7, read our announcement!

Support for C# 11 and F# 7

As part of the upgrade to .NET 7, Polyglot Notebooks now has support for C# 11 and F# 7. To see all the exciting new features you can use in Polyglot Notebooks, review the following resources:

Improvements to SQL and KQL with the new dynamic kernel picker

When establishing a connection with a Microsoft SQL Server or Kusto Cluster, you need to alias the connection using the –kernel-name parameter in the #!connect command. In order to then declare which database connection you want to query against, you previously would have had to add a magic command using the alias at the beginning of each cell.

Before the dynamic kernel picker:

With the dynamic kernel picker, you can now declare which database connection you are querying in the bottom right of the cell instead of using a magic command. Simply add a new code cell after establishing your connection, click on the dynamic kernel picker, and select the alias you created for your connection. Then write your native SQL or Kusto code!

    Is there any plans for adding extension for visual studio (not code) 2022 ? Given the large focus on supporting various .Net language and that visual studio is a powerfool tool for many .Net developers.

    I would love to jump into this in a big way, but I now have major “abandonment issues” when it comes to all things Microsoft.

    These are one of the coolest things no one else has noticed yet, for sure. Been using it for a little while now and it’s really phenomenal! You can basically make documentation or tutorials for onboarding new employees or training junior devs (whatever you imagine) and then you can run it whenever you want, one click, no console application project template or anything. You can put a demo in one of these for clients to show how your SDK or web API works, I’m realizing you’re only really limited by creativity. I like having the notebook open in VS Code while I work in Visual Studio or Rider, as I can test a NuGet package in seconds and see if I like it and if it solves the issue I had in mind. I’d really like to see more effort and resources go into powering this thing up and extending the capabilities. I really want to have it in a stand-alone form and as a VSIX extension for VS 2022.

    I applaud everyone who’s been working on this, I would not have imagined it would be this cool and useful, I guess because I wasn’t imaginative enough to think of combining it with a markdown editing system and letting you insert arbitrary “blocks” of any language wherever you want to. So, yesssss, MORE PLEASE!!! Love it!!!

    this is painful as .net 7 is not LTS. I would ask to support .NET 6.0 as well!
