Description Jan Krivanek 2016-06-07 17:34:35 UTC
When creating SqlBulkCopy with connection string and calling WriteToServer one will get 'This method should not be called on a closed connection' InvalidOperationException.

Exception is thrown here: https://github.com/mono/mono/blob/master/mcs/class/System.Data/System.Data.SqlClient/SqlBulkCopy.cs#L383 After chceking that connection is in Closed state.
However if you use one of the ctor receiving just connection string - e.g. https://github.com/mono/mono/blob/master/mcs/class/System.Data/System.Data.SqlClient/SqlBulkCopy.cs#L88
Connection is only created (which leaves the default value of connection state - Closed. See: https://github.com/mono/mono/blob/master/mcs/class/System.Data/System.Data.SqlClient/SqlConnection.cs#L108) but never opened

Mono 5.10 has significantly improved System.Data implementation which should resolve this issue. If you can still reproduce it please reopen the issue.
