Interview Questions For Net Developer – CTS stands for Common Type System. It follows a set of structural rules in which data types must be declared and used in program code. It is used to describe all data types used in an application. We can create our own classes and functions based on CTS rules. It helps to call a data type declared in one programming language by another programming language.
The Common Language Specification (CLS) allows developers to use cross-language components with certain rules that come with CLS. It also helps to reuse your code between all languages supported by .NET.
