Symptoms
When you create a new data connection to an Oracle database with the ODBC Driver (Microsoft OLE DB Provider for ODBC Drivers) in Server Explorer, the data connection does not appear in the Data Adapter Configuration Wizard of the OdbcDataAdapter.
Resolution
Connecting to Oracle databases through ODBC is not supported by Visual Studio .NET. Therefore, the data connection does not appear in the Data Adapter Configuration Wizard of Visual Studio .NET.
