Why is this an issue?
Consistent use of "None" in flags enumerations indicates that all flag values are cleared. The value 0 should not be used to indicate any other
state, since there is no way to check that the bit 0
is set.
Noncompliant code example
<Flags()>
Enum FruitType
Void = 0 ' Non-Compliant
Banana = 1
Orange = 2
Strawberry = 4
End Enum
Compliant solution
<Flags()>
Enum FruitType
None = 0 ' Compliant
Banana = 1
Orange = 2
Strawberry = 4
End Enum
