## Why is this an issue?

Creating an extension method that extends `Object` is not recommended because it makes the method available on every type. Extensions should be applied at the most specialized level possible, and that is very unlikely to be `Object`.

### Noncompliant code example

    Imports System.Runtime.CompilerServices

    Module MyExtensions
        <Extension>
        Sub SomeExtension(obj As Object) ' Noncompliant
            ' ...
        End Sub
    End Module
