Hi
Susja •,,
Azure Data Studio is built on top of Visual Studio Code and offers a lightweight, keyboard focused modern code workflow experience when working with SQL Server, Azure SQL Database, and Azure Synapse Analytics.

If your ask is like Can I use Visual Studio Code (VS Code) extensions with Azure Data Studio?
Yes.
However, not all VS Code extensions translate to Azure Data Studio.
Regarding your second question, it is replied over another question raised by you.
Hope this helps. Thanks.
