How to: Create a Database Connection

The database features that are included in Visual Studio make use of one or more database connections. Before you can connect to a database, you must create the connection. You can create a connection by clicking New Connection in the following dialog boxes:

  • Data Compare dialog box

  • Schema Compare dialog box

  • Connect to Server dialog box for the Transact-SQL editor

  • Generate Data for Target Database dialog box for Data Generator

  • Database Test Configuration dialog box for database unit testing

You can also add a connection by using Server Explorer. For more information, see How to: Connect to a Database from Server Explorer.

Important noteImportant

You can remove connections only from Server Explorer.
