What is Common Laguage Specification in ASP.NET? or What is CLS in ASP.NET?

Common Laguage Specification (CLS)

Common language specification is the sub-set of the Common type system(CTS).This is provide the cross language interoperability.

For Example:

VB .Net’s Integer is 32 bit which maps exactly to the IL Type int32

and C#  .Net’s int is 32 bit which maps exactly to the IL Type int32

    i.e              int (In C#)——––>  int32 (In IL) <–———- integer (In VB)

int (In C#) and Integer(In VB) both are exactly mapped to  int 32(In IL).
