Hello there,
I am trying to use NHibernate with Spring.Net und mySQL 5. However, when setting up the connection and creating the SessionFactoryObject, I get this InvalidCastException:
NHibernate seems to cast MySql.Data.MySqlClient.MySqlConnection to System.Data.Common.DbConnection which causes the exception.
System.InvalidCastException wurde nicht behandelt.
Message="Das Objekt des Typs \"MySql.Data.MySqlClient.MySqlConnection\" kann nicht in Typ \"System.Data.Common.DbConnection\" umgewandelt werden."
Source="NHibernate"

InnerException:
I am using the programmatically setup approach in order to get a quick NHibernate Setup. Here is the setup Code:
Configuration config = new Configuration();
Dictionary props = new Dictionary();
props.Add("dialect", "NHibernate.Dialect.MySQL5Dialect");
props.Add("connection.provider", "NHibernate.Connection.DriverConnectionProvider");
props.Add("connection.driver_class", "NHibernate.Driver.MySqlDataDriver");
props.Add("connection.connection_string", "Server=localhost;Database=orm_test;User ID=root;Password=password");
props.Add("proxyfactory.factory_class", "NHibernate.ByteCode.Spring.ProxyFactoryFactory, NHibernate.ByteCode.Spring");
config.AddProperties(props);
config.AddFile("Person.hbm.xml");
ISessionFactory factory = config.BuildSessionFactory();
ISession session = factory.OpenSession();
Is something missing? I downloaded the current mysql Connector from the mysql Website.
