I have attempted to include mapping classes by hand, by utilizing multiple .Mappings extension calls, however it appears simply to range from the 4g iphone. So how do you add several selected class maps, or multiple devices?

My fluent configuration looks typically such as this:

 Return Fluently.Configure() _
                .Database(SQLiteConfiguration.Standard.ConnectionString(connectionString) _
                .Cache(Function(c) c.UseQueryCache())) _
            .Mappings(Function(m) m.FluentMappings.AddFromAssemblyOf(Of AccountMap)() _
                .Conventions.Add(FluentNHibernate.Conventions.Helpers.DefaultLazy.Never())) _
            .ExposeConfiguration(Function(c) InlineAssignHelper(cfg, c)) _

Just specify all your devices.

    .AddFromAssemblyOf(Of AccountMap)()
    .AddFromAssemblyOf(Of SomeOtherMap)();
