+### Except for Cases
+
+For `Object` in some cases, you still have to explicitly specify `ObjectWrapper` type.
+
+Examples:
+
+When declaring a variable or a function return type:
+
+```cpp
+/* function parameters and return types */
+MyDto::ObjectWrapper foo(const MyDto::ObjectWrapper& parameter) {
+
+  /* declaring a variable */
+  MyDto::ObjectWrapper myDto = MyDto::createShared(); 
+
+  auto myDto = MyDto::createShared(); // better.
+
+  return myDto;
+}
+```
