If I create and dispose my container multiple times, on each creation I noticed, due to typed factory, a big memory allocation(200kb for this sample, but into a real app ~2MB) that leads to OutOfMemory Exception
W/o factory autogeneration memory grows much slower.
//using auto-created factory -> memory grows much much more...(see task mngr)
Component.For().AsFactory(c => c.SelectedWith())
//using my Factory w/o -> memory grows much less
//Component.For().ImplementedBy(),
