Compiler Warning (level 1) CS3008

Identifier 'identifier' differing only in case is not CLS-compliant

A public, protected, or protectedinternal identifier breaks compliance with the Common Language Specification (CLS) if it begins with an underscore character (_).For more information on CLS Compliance, see Writing CLS-Compliant Code and Common Language Specification.


The following example generates CS3008:

// CS3008.cs

using System;

public class a
    public static int _a = 0;  // CS3008
    // OK, private
    // private static int _a1 = 0;

    public static void Main()
