I think you should have a option that you can turn on and off that will allow will automap the properties of a complex type. Lets say you have a complex type Complex1 that has these two properties int0 and int1 and you add two Complex1 types to your class the source will map to the same location and causes a exception when you try to create the database. There is a message thread here about this: http://forums.devart.com/viewtopic.php?f=31&t=24081

I really consider this a bug
