Salve ragazzi,
ho creato un webservice, che dei metodi, l'ho pubblicato, e alla prima richiesta di un methodo da un'applicazione che ho fatto in visual basic.net mi viene mostrato questo mesaggio:

codice:
Eccezione non gestita di tipo "System.Web.Services.Protocols.SoapException" in system.web.services.dll

Informazioni aggiuntive: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Net.Sockets.SocketException: A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied
   at System.Net.Sockets.Socket.Shutdown(SocketShutdown how)
   at MySql.Data.Common.SocketStream.Read(Byte[] buffer, Int32 offset, Int32 count)
   at System.IO.BufferedStream.ReadByte()
   at MySql.Data.MySqlClient.PacketReader.ReadHeader()
   at MySql.Data.MySqlClient.PacketReader.OpenPacket()
   at MySql.Data.MySqlClient.NativeDriver.Open()
   at MySql.Data.MySqlClient.MySqlPool.CreateNewPooledConnection()
   at MySql.Data.MySqlClient.MySqlPool.GetPooledConnection()
   at MySql.Data.MySqlClient.MySqlPool.GetConnection()
   at MySql.Data.MySqlClient.MySqlPoolManager.GetConnection(MySqlConnectionString settings)
   at MySql.Data.MySqlClient.MySqlConnection.Open()
   at System.Data.Common.DbDataAdapter.QuietOpen(IDbConnection connection, ConnectionState& originalState)
   at System.Data.Common.DbDataAdapter.FillFromCommand(Object data, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
   at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
   at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable)
   at mioPrg.DB.login(String password, String account, String pwd)
   --- End of inner exception stack trace ---

Mi sembra di capire che si tratti di un problema di riferimenti del progetto più precisamente alla dll. di mysql... cosa devo fare esattamente per risolvere il problema?

Grazie
