### Change Description

|
|
|
|
|
|
|
|
Beginning in the .NET Framework 4.5.1, the .NET Framework will attempt to
|
|
|
|
|
automatically reconnect broken SQL connections. Although this will typically
|
|
|
|
|
make apps more reliable, there are edge cases in which an app needs to know that
|
|
|
|
|
the connection was lost so that it can take some action upon reconnection.

|
|
|
|
|
|
|
|
If this feature is undesirable due to compatibility concerns, it can be disabled
|
|
|
|
|
by setting the
|
|
|
|
|
<xref:System.Data.SqlClient.SqlConnectionStringBuilder.ConnectRetryCount?displayProperty=name>
|
|
|
|
|
property of a connection string (or
|
|
|
|
|
<xref:System.Data.SqlClient.SqlConnectionStringBuilder?displayProperty=name>) to
|
|
|
|
|
0.

### Notes
|
|
|
|
|
It would be very difficult to know if code depended on not auto-reconnecting and ADO.NET connection.
