使用System.Data.OracleClient配置Fluent NHibernate

Question

我正在尝试使用System.Data.OracleClient而不是Oracle.DataAccess和Fluent Nhibernate。据我所知，为了实现这一点，我应该将我的驱动程序从OracleDataClientDriver改为OracleClientDriver。我已经像下面这样对它进行了配置，但我得到了一个错误，看起来它仍然在尝试使用OracleDataClientDriver。我做错了什么？

FluentConfiguration configuration = Fluently.Configure()                
            .Database(
            OracleDataClientConfiguration.Oracle10
            .ConnectionString(x => x.FromConnectionStringWithKey(connString))
            .Provider<NHibernate.Connection.DriverConnectionProvider>()
            .Driver<NHibernate.Driver.OracleClientDriver>()            
               )

这就是错误，它仍然在寻找我试图摆脱的Oracle.DataAccess。

使用OracleClientConfiguration和OracleClientDriver而不是OracleDataClientConfiguration和OracleDataClientDriver

FluentConfiguration configuration = Fluently.Configure()                
            .Database(
            OracleClientConfiguration.Oracle10
            .ConnectionString(x => x.FromConnectionStringWithKey(connString))
            .Provider<NHibernate.Connection.DriverConnectionProvider>()
            .Driver<NHibernate.Driver.OracleClientDriver>()            
               )
