What is Common Language Specification (CLS)

The CLS defines the minimum standards that .NET languages must confirm.

Compliant Producer
The components in the language can be used by other language.

Consumer
The language can reuse classes produced in any other language.
This basically means the ability to instantiate classes.


Extender
Languages in this category can do more than just instantiate classes – they can also extends those classes using the inheritance feature of .Net
