The type name 'CVL' does not exist in the type 'CVL.CVL Error

I am trying to access a public method in my Master Page from my child pages.  Here is the basic layout that I have:

CVL.Master - Master page
CVL.Master.cs
============
namespace CVL
{
    public partial class CVL : System.Web.UI.MasterPage
    {
            public void ErrorHandling(parameter definitions)
            {
                     error handling code
            }
    }
}

CVLLookup.aspx - Web page using CVL.Master as it's Master Page
CVLLookup.aspx.cs
===============
namespace CVL
{
    public partial class CVLLookup : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs, e)
        {
             CVL pm = (CVL)Page.Master;
             pm.ErrorHandling(parameters);
        }
    }
}

Select allOpen in new window

I get the above error in the CVLLookup.aspx.designer.cs file which is autogenerated.  Here is what is generated in the designer file:

public new CVL.CVL Master {
    get {
        return ((CVL.CVL)(base.Master));
    }
}

The error occurs on the second reference to CVL.CVL in both places.  See attached file.

Any help is greatly appreciated!
