title: Moving Solution from vs 2010 to vs 2012 gives the following error
body: <blockquote>
    <p>Error 15 'custom ribbonclass' does not implement interface member
    'Microsoft.Office.Tools.Ribbon.RibbonComponent.RibbonUI', 
    'Microsoft.Office.Tools.Ribbon.RibbonComponent.ResumeLayout(bool)'</p>
  </blockquote>
  
  <p>and many more similar errors.</p>
  
  <p>Can anyone help me with this?
  Here is part of the file that is giving all the errors.</p>
  
  <p>from the file Stjonbord.designer.cs</p>
  
  <pre><code>namespace VefKennsla
  {
      partial class Stjonbord : Microsoft.Office.Tools.Ribbon.OfficeRibbon
      {
          private System.ComponentModel.IContainer components = null;
  
          public Stjonbord()
          {
              InitializeComponent();
          }
  
          #region Component Designer generated code
  
          private void InitializeComponent()
          {
              this.Stjornbord = new Microsoft.Office.Tools.Ribbon.RibbonTab();
              this.grBil = new Microsoft.Office.Tools.Ribbon.RibbonGroup();
  </code></pre>
  
  <p>This is designer gererated code but it gives lot of errors like this line</p>
  
  <p>this.Stjornbord = new Microsoft.Office.Tools.Ribbon.RibbonTab();</p>
  
  <p>gives this error:
  Error   36  Cannot create an instance of the abstract class or interface 'Microsoft.Office.Tools.Ribbon.RibbonTab'  ...\Stjonbord.designer.cs   </p>
