Why is this an issue?
Having a field in a child class with a name that differs from a parent class' field only by capitalization is sure to cause confusion. Such child
class fields should be renamed.
Noncompliant code example
Public Class Fruit

    Protected PlantingSeason As String

    ' ...

End Class

Public Class Raspberry
    Inherits Fruit

    Protected Plantingseason As String  ' Noncompliant

    ' ...

End Class

Compliant solution
Public Class Fruit

    Protected PlantingSeason As String

    ' ...

End Class

Public Class Raspberry
    Inherits Fruit

    Protected WhenToPlant As String

    ' ...

End Class

Or
Public Class Fruit

    Protected PlantingSeason As String

    ' ...

End Class

Public Class Raspberry
    Inherits Fruit

    ' Field removed, parent field will be used instead

End Class

Exceptions
This rule ignores same-name fields that are Shared in both the parent and child classes. It also ignores Private parent
class fields and fields explicitly declared as Shadows, but in all other such cases, the child class field should be renamed.
