Question

Sudeep Chourasia · Answer

CLS stands for the Common Language Specification. It's the minimal set of rules and required language features that a .NET language must implement and understand. This set is a subset of the common type system which defines how types are defined in .NET. Being CLS compliant means that you can write code that can be consumed by any language that can be compiled and run on the CLR. But CLS compliance is not required giving you the flexibility in cases where CLS compliance would be hard or impossible to do. If you intend your code to be consumed by other developers your API (your public classes and methods) should be CLS compliant. You should declare this by adding the CLSCompliantAttribute to your assemblies. If you are not writing for others CLS compliance is not necessary. When your assembly is marked with the CLSCompliantAttribute the compiler will (should!) check your code to see if when compiled it will violate any of the CLS rulesand report violations to you for fixing.

Hi A Word from Dathan : CLS-compliance is particularly important if you're distributing libraries - specifically writing CLS compliant guarantees that your libraries will be usable by all CLS-compliant languages.
