Fluent nHibernate Confiiguration Error

Question

i m doing the configuration of Fluent nHibernate in my application with the following code ,

var FNHConfig = Fluently.Configure()
                .Database(MsSqlConfiguration.MsSql2008
                    .ConnectionString(c => c.FromConnectionStringWithKey("FNHConnection"))
                    )
                    .Mappings(m => m.FluentMappings.AddFromAssembly(Assembly.GetCallingAssembly()))
                    .BuildConfiguration();

            return FNHConfig.BuildSessionFactory();

but it giving exception saying that "An invalid or incomplete configuration was used while creating a SessionFactory. ". anyone have idea how to solve this exception ?

Thanks

I think you will have an issue with your FluentMaps somewhere rather than it being the configuration. — Mark Perry
m => m.FluentMappings.AddFromAssembly(Assembly.GetCallingAssembly() , GetCallingAssembly is my DAL assembly , which do not have mapping define over there, should i have to define mapping in DAL ? — Saad

It's most likely a mapping problem like Mark says above but you need to provide more detail. That is the generic outer exception that is thrown if you fail to build the Session Factory.

try
{
    var FNHConfig = Fluently.Configure()
            .Database(MsSqlConfiguration.MsSql2008
                .ConnectionString(c => c.FromConnectionStringWithKey("FNHConnection"))
                )
                .Mappings(m => m.FluentMappings.AddFromAssembly(Assembly.GetCallingAssembly()))
                .BuildConfiguration();

        return FNHConfig.BuildSessionFactory();
}
catch (Exception ex)
{
    Console.WriteLine(ex.ToString());
}

Take a look at the error in the console window and you will most likely be lead to the culprit of this exception.
