Default Template produce Error. ThisRibbonCollection : GetRibbon

Question

I create a Excel 2010 Addin project in Visual Studio 2010 [Targeting .NET 4.0 Client profile, by default]

I create a Folder within my project.

Add a Ribbon [Designer] Control in newly created folder.

Add some UDF class in seperate folder.

Compile and get this error

'xxx.xxx.ThisRibbonCollection' does not contain a definition for 'GetRibbon' and no extension method 'GetRibbon' accepting a first argument of type 'xxx.xxx..ThisRibbonCollection' could be found (are you missing a using directive or an assembly reference?)

Here is auto generated code for the same.

partial class ThisRibbonCollection
    {
        internal AcousticalRibbon AcousticalRibbon
        {            
            get { return this.GetRibbon<AcousticalRibbon>(); }
        }
      
    }

I read in older blog post, referring mainly to VSTO 3.0 [I am using VSTO 4.0] to extend this class with MS.Office.Tools.Ribbon.RibbonReadOnlycollection, However when I did that it ask to implement other Interface method, which are though some basic method of object, but not sure what to write code for them and hence I am not very please to implement them unless that is the only method. Any idea why I am getting this error ?

I just create a new TEST project using Template EXCEL 2010 AddIn, Add Ribbon Designer into this. And Get Same error, so I am sure my custom code is not a problem there. Any Idea ?

Okay, This is wired but the problem was in using a FOLDER to put ribbon. In order to organize my code, I have put ribbon in a folder. This cause the ThisRibbonCollection loose its namespace with Basic application. So I just modify the partial class and take it out of PRoject.Folder to Project Namespace and correct reference.
