我是 NHibernate 的新手，所以如果我问了一个愚蠢的问题，请放轻松...

我正在关注此处发布的 NHibernate 教程，并收到“HibernateException”类型的运行时错误

有问题的代码如下所示：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using FirstSolution;
using NHibernate.Cfg;
using NHibernate.Tool.hbm2ddl;
using NUnit.Framework;

namespace FirstSolution.Tests
{
    [TestFixture]
    public class GenerateSchema_Fixture
    {
        [Test]
        public void Can_generate_schema()
        {
            var cfg = new Configuration();
            cfg.Configure();
            cfg.AddAssembly(typeof(Product).Assembly);

            new SchemaExport(cfg).Execute(false, true, false);
        }
    }
}

我收到错误的行是：

cfg.AddAssembly(typeof(Product).Assembly);

最里面的例外是：

The IDbCommand and IDbConnection implementation in the assembly System.Data.SqlServerCe could not be found

这是我的堆栈跟踪：

我已经确定它System.Data.SqlServerCe已被引用并且它的Copy Local属性设置为True. 但是，错误仍然存​​在。您的帮助将不胜感激。谢谢。

复制作为评论的答案，因为事实证明是这样的：

确保添加对 System.Data.SqlServerCe 的引用并CopyLocal=true在主项目和测试项目上进行设置。
