Hence the changes to the values. Let's say b: struct A { int data; B b; }; To do that, the compiler needs to already know what B is, so declare that struct before you declare A. The only times a struct property has a real advantage over a structure field are when the property is defined as doing something that could not be accomplished by reading a field (in which case an auto-property wouldn't be suitable), when the structure needs to implement an interface that exposes a property, or when the struct has to be usable. BrickGame should be able to do exactly what you say. In fact, it will fail when one of the struct members is a compound C++ type that normally requires a call to a (copy-) constructor to be initialized corectly - one obvious example would be std::string.
