namespaces in custom libraries best practices
<p>Just wondering what the pros and cons between the two following two examples:</p>

<pre><code>using MyLib;

namespace System.IO
{
    public class IoService : IIoService
    {
    ...
</code></pre>

<p>and</p>

<pre><code>using System.IO;
using MyLib;

namespace MyLib.IO
{
    public class IoService : IIoService
    {
    ...
</code></pre>
