Why does compiler complain when I try to convert to a base-class?

class BaseClass
{
 ...
};

class SubClass
{
 ...
};

class MyApp
{
 SubClass *pObject;

 BaseClass *getObject()
 {
  return pOject;
 }
};

I get a compiler error: error C2440: 'return' : cannot convert from 'SubClass *' to 'BaseClass *'

Why doesn't it work, surely you can automatically convert to a base-class without any casting?
