Then the CLS police would come knocking!

Not CLS-compliant means that the type may not be available in other .NET languages. It would become a regular, signed Int16.

>I have a two byte number (0-65535) and UInt16 would work great to represent this number. I have in the past simply used Int32 and added my own error checking to make sure the number is in the range I want it to be. Should I stick with Int32 or should I go non-compliant and use UInt16? (the motivation for researching this is to potentially save 2 bytes of memory <s>)
