camel_case_types

The type name '{0}' isn't an UpperCamelCase identifier.

The analyzer produces this diagnostic when the name of a type (a class, mixin, enum, or typedef) doesn't use the 'UpperCamelCase' naming convention.

The following code produces this diagnostic because the name of the class doesn't start with an uppercase letter:

class c {}

Rename the type so that it has a valid name:

class C {}
