**CLS known as Common Language Specification** which is subset of CTS (Common type system), it is defined as the set of rules and restriction that must be follow by all languages that **[run on .net platform](https://www.mindstick.com/forum/145569/what-is-the-role-of-jit-compiler-in-dot-net-framework)**. In order to communicate between the objects of different languages, CLS is used. Also it ensures interoperability among different languages in .Net framework.
