Remarks

This class provides connection and execution information to the Execute method when the Transact-SQL is executed. ConnectionContext uses types in the System.Data.Common namespace, regardless of database type.

Use this type to store the state of an open connection for later use. For example, you can save the impersonation context from an open connection if you want to use the same connection string and Windows authentication with two sets of Windows credentials. For more information, see Impersonate. You must release the context in the Dispose method.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
