Common Type System

• In order to communicate smoothly with two language in CLR has CTS (Common Type System).
• Example 
• in VB you have “Integer” and in C++ you have “long” these data types are not compatible so the interfacing between them is very complicated. 
• In order to able that two different languages the.NET Framework 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.
