+Microsoft SQL Server Express LocalDB is a feature of [SQL Server Express](../../sql-server/editions-and-components-of-sql-server-version-15.md) targeted to developers. It is available on SQL Server Express with Advanced Services.
 
 LocalDB installation copies a minimal set of files necessary to start the [!INCLUDE[ssDEnoversion](../../includes/ssdenoversion-md.md)]. Once LocalDB is installed, you can initiate a connection using a special connection string. When connecting, the necessary [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] infrastructure is automatically created and started, enabling the application to use the database without complex configuration tasks. Developer Tools can provide developers with a [!INCLUDE[ssDEnoversion](../../includes/ssdenoversion-md.md)] that lets them write and test [!INCLUDE[tsql](../../includes/tsql-md.md)] code without having to manage a full server instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)].

 The easiest way to use LocalDB is to connect to the automatic instance owned by the current user by using the connection string `Server=(localdb)\MSSQLLocalDB;Integrated Security=true`. To connect to a specific database by using the file name, connect using a connection string similar to `Server=(LocalDB)\MSSQLLocalDB; Integrated Security=true ;AttachDbFileName=D:\Data\MyDB1.mdf`.
 
 >[!NOTE]
->The first time a user on a computer tries to connect to LocalDB, the automatic instance must be both created and started. The extra time for the instance to be created can cause the connection attempt to fail with a timeout message. When this happens, wait a few seconds to let the creation process complete, and then connect again.
