The Debug menu can be used to launch your extension into a special instance of Azure Data Studio with or without the VS Code debugger attached.
The template extension demonstrates two concepts - extension activation and extension commands. On extension activation, a message is logged to the extension console. On execution of the "Hello World" command, an information message is presented to the user.
Open the Debug menu and select Start Debugging. A new Azure Data Studio window should open and VS Code should enter debugging mode.
In Azure Data Studio, open the command pallette (ctrl + shift + p) and type in Hello World.
When you hit enter, an information message will appear in the lower right corner.
We have a functioning, albeit not very useful, Azure Data Studio extension
- Open an Azure Data Studio window prior to starting debugging
- Ensure that Azure Data Studio is in your PATH
