System).Example in VB you have “Integer” and in C++ you have “long” these datatypes are not
compatible so the interfacing between them is very complicated. In order that these two different
languages communicate Microsoft introduced Common Type System. So “Integer” data type in
VB6 and “int” data type in C++ will convert it to System.int32, which is data type of CTS. CLS,
which is covered in the coming question, is subset of CTS.
