In Azure Data Studio, new features and improvements are often first released as preview features before they're made generally available (GA). The amount of time a feature remains in preview can vary based on user feedback, quality checks, and long-term road maps. By enabling preview features, you get full access to Azure Data Studio features and the chance to provide early feedback.
How do I enable preview features?
On first launch
If you're a new user, you can opt into preview features when you launch Azure Data Studio for the first time. On startup, a toast notification appears in the bottom-right corner of the screen that gives you the option to enable or disable preview features. Select Yes (recommended) to enable preview features.
In Settings
You can enable or disable preview features at any time in Settings.
Select the Gear icon in the bottom-left corner and then select Settings from the context menu.
Once the Settings tab is open, type "enable preview features" in the search bar.
To enable preview features, check the checkbox for Enable unreleased preview features under Workbench: Enable Preview Features. To disable preview features, clear the checkbox.
