A namespace name or a type name matches a reserved keyword in a case-insensitive comparison.

Identifiers for namespaces and types should not match keywords defined by languages that target the common language runtime. Depending on the language in use and the keyword, compiler errors and ambiguities can make the library difficult to use. This rule does not check all keywords in all .NET languages.

Select a name that does not appear in the list of keywords.

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