Cause

The names of two types, members, parameters, or fully qualified namespaces are identical when converted to lower-case.

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.

How to Fix Violations

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

When to Exclude Warnings

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

Identifiers should be cased correctly

Long acronyms should be pascal-cased

Short acronyms should be uppercase
