我正在尝试使用 System.Data.OracleClient 而不是 Oracle.DataAccess 和 Fluent Nhibernate 。据我了解，为了实现这一点，我应该将驱动程序从 OracleDataClientDriver 更改为 OracleClientDriver。我已经像下面这样配置它，但我收到一个错误，看起来它仍在尝试使用 OracleDataClientDriver。我究竟做错了什么？

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

这是错误，它仍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>()            
               )

问题中的评论解决了我的问题。为了他人的利益，我发布了这个答案，@PapaBurgundy 和 @Rivarolle 的答案值得充分肯定。
