== Why is this an issue?
By default the storage type of an ``++enum++`` is ``++Int32++``. In most cases it is not necessary to change this. In particular you will not achieve any performance gain by using a smaller data type (e.g. ``++Byte++``) and may limit future uses.
=== Noncompliant code example
[source,text]
----
using System;
namespace MyLibrary
{
public enum Visibility : sbyte // Noncompliant
Visible = 0,
Invisible = 1,
}
=== Compliant solution
public enum Visibility
