- fixed behavior of Container.SaveBlob (file was not being overwritten)
- added support for default value in the entity converter
- fix scaleset size data type
- added initialization of Subnet
- renamed TestHook Info to _Info to prevent clashing of name function mame
- added target framework to ApiServiceProject to help local debugging
