CLS defines rules that languages running on the .NET framework must follow to ensure code can be consumed by any .NET language. Specifically, it specifies that languages cannot have members with the same name that only differ by case, like add() and Add(), since this would work in a case-sensitive language like C# but not a case-insensitive one like VB.NET. Following CLS standards helps provide cross-language interoperability.

1. CLS in .NET
Learn CLS(Common Language
Specification) with an example.

2. CLS stands for Common Language
Specification.
It is set of rules that every language must
follow which runs under .NET framework.
When it follows the rules it will ensure
that code can be consume in any .Net
compiled language

3. For example:-
we cannot have members with
same name with case difference
i.e. add() and Add() methods. It can
work easily in C# as it is case-
sensitive but it is not possible in
VB.NET because it not cas-
sensitive.
