A network-related or instance-specific error...

I'm following a tutorial in Pro ASP.NET MVC 5 page 170.  Under "Creating the Database", it says to go to Server Explorer > Choose Data Source, Select Microsoft SQL Server, Continue, enter server name (localdb)v11.0, Use Windows Authentication, Select or enter a database name: SportsStore.

When I test the connection I see the error: A network-related or instance-specific error...

I tried replacing (localdb)v11.0 with LocalDB but got the same error.

What else should I try?

Do you have MS SQL Server installed ?  If so, is it the express version ?

make sure you have provided correct Server name when you connecting to the database.

and make sure the MS SQL service is running fine?

Are you trying to connect to a SQL Server named instance or the default instance?
It will help if you can post a print screen of the configurations that you're using.

Went into the installer and selected Workloads > .net Desktop Development > SQL Server Express 2016 LocalDB.   I don't remember having to explicitly select that before.  Then in the Server Explorer I entered Server Name (localdb)\MSSQLLocalDB , which I read somewhere else. That worked.  LocalDB and LocalDB)\V11.0 didn't work.  Thanks for your help!
