title: FluentNhibernate, add mappings from multiple assemblies
body: <p>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? </p>
  
  <p>My fluent configuration looks typically like this: </p>
  
  <pre><code> 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()
  </code></pre>
