Hi Pablo_Lerner If only it were that easy! If we only develop in SSMS, then we exclude all users who run on Linux and macOS. We could expand the functionality of the mssql extension in VS Code, but there are significant limitations that make a complete experience unlikely. Moving everything that's in SSMS to ADS would take...years...so even if we would go that route, we would still have to maintain SSMS until the work is complete. Understand that we do have these conversations internally. We are not ignoring feedback; there are a lot of factors - some that are not publicly shared - that impact these decisions.
I'm happy to review a list of what you think is missing from SSMS to make it more optimal for admins and devs. I can't promise anything, but I'm always open to feedback.
