The projects in this directory provide examples of how you can create and publish .NET Interactive kernel extensions.
The ClockExtension sample builds a standalone extension that adds a magic command and applies custom formatting in order to visualize System.DateTime using an SVG rendering of a clock. This example is fairly simple because it only works with types already referenced by .NET Interactive. You can see a walkthrough showing how to build and install the extension in this notebook.
The Library sample is more complex. This sample illustrates how you can augment your own libraries with notebook-specific enhancements that will be available when someone uses you library in .NET Interactive, but without adding a direct dependency from your library to .NET Interactive.
The RandomNumber extension shows how to build a script-based extension with no direct dependency on the Microsoft.DotNet.Interactive libraries. See README.md in that directory for more information.
