Visual Studio SDK: Error Cannot implicitly convert type ‘…MyUserControl' to 'System.Windows.Forms.IWin32Window'

I am creating a Visual Studio options page exactly as described in the example - Walkthrough: Creating an Options Page located athttp://msdn.microsoft.com/en-us/library/bb166195.aspx- I am receiving the following error - Cannot implicitly convert type '...MyUserControl' to 'System.Windows.Forms.IWin32Window'' as I return the usercontrol page to IWin32Window for the following code:

[Browsable(false)]
[DesignerSerializationVisibility(
	DesignerSerializationVisibility.Hidden)]
protected override IWin32Window Window
{
	get
        {
        	MyUserControl page = new MyUserControl();
                page.optionsPage = this;
                page.Initialize();               
                return page;
        }            
}

I tried explicit conversion and received and an invalid cast exception. The platform is Windows 8.1 and Visual Studios 2013 update 2.
