The underlying database or development environment might treat type names as case-insensitive, leading to a perceived duplicate even if the casing differs slightly.
Incorrect Schema/Namespace
The user is attempting to create a type in a schema or namespace where a type with the same name already exists, rather than the intended unique scope.
