After installing Visual Studio 2017 with the SQL Server Data tools feature checked, I noticed LocalDB was not installed. How can I add SQL Server LocalDB 2016 to my Visual S
New to the conversation, but wanted to share what I ran into because it may not be apparent that localdb was installed already. Here's another step you can take to verify.
I ran into this same issue and found out that I'd already installed localdb via desktop.
I was getting a connection string error and thought I did something wrong, but what I ended up doing is opening the SQL Server Object Explorer from within Visual Studio and sure enough, it was there.
Shortcut, Ctrl+\ & Ctrl+S, or View -> SQL Server Object Explorer.
