Using .NET Interactive as a Jupyter kernel

To use the .NET Interactive kernel for your multi-language notebooks in Jupyter Notebook, JupyterLab, and other Jupyter frontends, you first need to register .NET Interactive as a kernel with Jupyter.

Make sure you have the following installed:

  • The .NET 8 SDK.

  • Jupyter. An easy way to install Jupyter is through Anaconda.

  • You can verify the installations by opening the Anaconda Prompt (Windows) or a terminal (macOS, Linux) and running the following commands to ensure that Jupyter and .NET are installed and present on the path:

> jupyter kernelspec list
  python3        ~\jupyter\kernels\python3
> dotnet --version
  8.0.100

(The dotnet minor version isn't important.)

  • Next, in an ordinary console, install the dotnet interactive global tool:
> dotnet tool install -g Microsoft.dotnet-interactive
  • Switch back to your Anaconda prompt and install the .NET kernel by running dotnet interactive jupyter install:
> dotnet interactive jupyter install
Installing using jupyter kernelspec module.
Installed ".NET (C#)" kernel.
Installing using jupyter kernelspec module.
Installed ".NET (F#)" kernel.
Installing using jupyter kernelspec module.
Installed ".NET (PowerShell)" kernel.
  • You can verify the installation by running the following again in the Anaconda Prompt. You should now see a kernelspec entry for each of the default supported .NET languages:
> jupyter kernelspec list
  .net-csharp        ~\jupyter\kernels\.net-csharp
  .net-fsharp        ~\jupyter\kernels\.net-fsharp
  .net-powershell    ~\jupyter\kernels\.net-powershell
  python3            ~\jupyter\kernels\python3

Updating .NET Interactive

To update to the latest version of .NET Interactive, open an ordinary console and run the following code:

> dotnet tool update -g Microsoft.dotnet-interactive

Running the .NET Interactive Jupyter kernel

To launch Jupyter, you can run either jupyter lab or jupyter notebook from your Anaconda Prompt, or you can launch Jupyter using the Anaconda Navigator.

Once Jupyter has launched in your browser, you have the option to create notebooks using C#, F#, or PowerShell.
