FluentNhibernate, add mappings from multiple assemblies

问题

I've tried to add mapping classes manually, by using multiple .Mappings extension calls, but it seems only to include the last one. So how do I add several selected class maps, or multiple assemblies?

My fluent configuration looks typically like 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)) _
            .BuildSessionFactory()

回答1:

Just specify all of your assemblies.

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

It looks like a lot of people including myself, doesn't find a complete solution to add all assemblies dropped in bin folder if they are anonymous. Anyhow, i did it like this, it's not optimal but its a solution..

    private static Conf CreateConfig()
    {
        return Fluently.Configure()
            .Database(DatabaseConfig)
            .Mappings(AddAssemblies)                
            .ExposeConfiguration(ValidateSchema)
            .ExposeConfiguration(BuildSchema)
            .BuildConfiguration();
    }

    private static void AddAssemblies(MappingConfiguration fmc)
    {
         (from a in AppDomain.CurrentDomain.GetAssemblies()
                select a
                    into assemblies
                    select assemblies)
                    .ToList()
                    .ForEach(a => 
                     {
                        //Maybe you need to inly include your NameSpace here.
                        //if(a.FullName.StartsWith("MyAssembly.Name")){
                        fmc.AutoMappings.Add(AutoMap.Assembly(a)
                            .OverrideAll(p => 
                            {
                                p.SkipProperty(typeof(NoEntity));
                            })
                            .Where(IsEntity));
                     }
          );
    }

    private static bool IsEntity(Type t)
    {
        return typeof(IEntity).IsAssignableFrom(t);
    }

    //Map IEntity
    public class User : IEntity{}
    public class UserMap : Entity<User>{}
    //UserMap inherits ClassMap<T>
