including using in namespace
<p>I have been wondering what is better way of using code.
Is there any difference between writing using inside of namespace:</p>

<p>ouside of namespace</p>

<pre><code>using System.Data.Entity;
using System.Web.Mvc;
using System.Web.Routing;
using Myproject.DataLayer;


namespace Myproject
{
  public class MyProjectClass{
  // etc
  }
}
</code></pre>

<p>Inside of namespace
 the only reason i can thing of : shorter names, and the complier does not need to go to global location to find the implementation... but not sure about the rest</p>

<pre><code>namespace Myproject
{
using System.Data.Entity;
using System.Web.Mvc;
using System.Web.Routing;
using DataLayer;

  public class MyProjectClass{
  // etc
  }
}
</code></pre>
