CLSCompliantAttributeCF 1.0, ECMA 1.0, serializable

System (mscorlib.dll)sealed class

This attribute indicates that a program element is compliant with the CLS. If you use non-CLS-compliant classes (such as UInt32) in a class marked as compliant, the compiler generates a compliance warning.

By default, types without this attribute are not CLS-compliant unless they are contained in a CLS-compliant type or assembly. You can specifically mark non-CLS-compliant members inside a CLS-compliant type using [CLSCompliant(false)].

public sealed class CLSCompliantAttribute : Attribute {
// Public Constructors
   public CLSCompliantAttribute(bool isCompliant);
// Public Instance Properties
   public bool IsCompliant{get; }
