I previously wrote about writing an extension for Azure Data Studio based on my experiences creating the First Responder Kit extension.  Since that post I had the opportunity to present on the topic at SQL Saturday in St.Paul, MN on October 6th, 2018.  I had a great time at SQL Saturday and more importantly, my demo worked!

This is the slide deck I presented and the link to the GitHub repository with more details on the demo:  https://github.com/dzsquared/AzureDataStudio_ExtensionDevelopment
