[Mono-list] Npgsql1.0 Protocol option not supported

[Andrus]

My C# application returns error

Protocol option not supported

Error occurs in line

Connection.Open();

Npgsql1.0 source code and docs does not contain such message.
When running under .NET 2 this error does not occur.

Any idea how to fix it ?

Environment:

Npgsql1.0
MONO 1.2  .net 2 profile
monocharge-20070112
Windows XP
VCS 2005 Express

Code where error occurs is:

public static void CreateConnection(string Server, string Database,
       string User, string Password) {

NpgsqlEventLog.Level = LogLevel.Debug;
NpgsqlEventLog.LogName = @"c:\NpgsqlLogFile.txt";

if (Connection != null)
    Connection.Close();

ConnectionString = "ENCODING=UNICODE;" +
       "SERVER=" + Server + ";" +
       "DATABASE=" + Database + ";" +
       "USER ID=" + User + ";" +
       "PASSWORD=" + Password + ";";

Connection = new NpgsqlConnection(ConnectionString);
IDbCommand Command = new NpgsqlCommand(@"
        SET search_path TO firma1,public;
        SELECT sfirmanimi FROM prpalk",
     (NpgsqlConnection)Connection);
// Follwing line causes error Protocol Option not supported in MONO
Connection.Open();
}
