== 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

[source,text]
----
using System;

namespace MyLibrary
{
    public enum Visibility
    {
        Visible = 0,
        Invisible = 1,
    }
}
