What is "Common Type System" (CTS)?

CTS( common type system) brings all .net languages data types on a common platform. It defines types like System.Int16, System.Int32 etc. A language may map 'int' to System.Int16 while another may map its 'int' data type to System.Int32.

Because all data types from all languages are mapped to common .net datatypes we can integrate code written in different .net languages into one assembly.
