NHibernate Tutorial Run-Time Error: HibernateException
- by Kashif
I'm a newbie at NHibernate so please go easy on me if I have asked a stupid question...
I am following the tutorial for NHibernate posted here and am getting a run-time error of type "HibernateException"
The code in question looks like this:
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);
}
}
}
The line I am getting the error at is:
cfg.AddAssembly(typeof(Product).Assembly);
The inner-most exception is:
The IDbCommand and IDbConnection implementation in the assembly System.Data.SqlServerCe could not be found
And here's my stack trace:

I've made sure that System.Data.SqlServerCe has been referenced and that its Copy Local property is set to True. The error persists, however. Your help would be appreciated. Thanks.
