Identifiers should differ by more than case







Breaking Change



The names of two types, members, parameters, or fully qualified namespaces are identical when they are converted to lowercase.

Rule Description

Identifiers for namespaces, types, members, and parameters cannot differ only by case because languages that target the common language runtime are not required to be case-sensitive. For example, Visual Basic is a widely used case-insensitive language.

This rule fires on publicly visible members only.

How to Fix Violations

Select a name that is unique when it is compared to other identifiers in a case-insensitive manner.

When to Suppress Warnings

Do not suppress a warning from this rule. The library might not be usable in all available languages in the .NET Framework.

Example of a Violation

The following example demonstrates a violation of this rule.

using System;
namespace NamingLibrary
    public class Foo    // IdentifiersShouldDifferByMoreThanCase    
        protected string bar;

        public string Bar        
            get { return bar; }        

Identifiers should be cased correctly
