The CLS (Common Language Specification) is a set of constraints on APIs and a complementary set of requirements on languages. If a library is CLS-compliant (i.e. adheres to all the constraints), then any CLS-compliant language can use that API. Conversely, a CLS-compliant language is guaranteed to be able to use any CLS-compliant library. (Int32 is an example of a CLS-compliant type, so CLS guarantees it's safe for library writers to use it in their APIs.)
