Property Value

String

The value of the TransactionBinding property, or Implicit Unbind if none has been supplied.

Remarks

The Transaction Binding keywords in a ConnectionString control how a SqlConnection binds to an enlisted Transaction.

The following table shows the possible values for the TransactionBinding property:

Value	Description
Implicit Unbind	The default. Causes the connection to detach from the transaction when it ends. After detaching, additional requests on the connection are performed in autocommit mode. The Current property is not checked when executing requests while the transaction is active. After the transaction has ended, additional requests are performed in autocommit mode.
Explicit Unbind	Causes the connection to remain attached to the transaction until the connection is closed or until EnlistTransaction is called with a null (Nothing in Visual Basic) value. An InvalidOperationException is thrown if Current is not the enlisted transaction or if the enlisted transaction is not active. This behavior enforces the strict scoping rules required for TransactionScope support.
