  Mapping for class 'Ram.WorkOrder' is specified in file 'config' but the class could not be found. --> RamEntitiesModel/namespace[Ram]/class[WorkOrder]
  
  I should mention that I am using the fetch method. A statement like this also gives me the error:
  

   

  Using dbContext As New RamEntitiesModel

   
      TextBox1.Text = dbContext.WorkOrders(1).WO_no.ToString

   

  End Using

  Hi Kyle,
  
   This error indicates that the app.config file has a mapping entry for class 'Ram.WorkOrder' but this class could not be found in the compiled assembly. Did you rename the class?
  You can use the 'Check Settings' dialog( Telerik->OpenAccess->Configuration->Check Settings menu entry) to automatically fix such problems.
  
  Do get back in case you need further assistance.
  
  All the best,

  I had to create a new solution and the problem was fixed and everything operates properly now.
  
  I attached a screen shot; my menu does not look how you described.
  
  Thanks.

  Hello Kyle,
  
  The entry I described is applicable for the 'Classic' approach of the product. You can switch between 'Classic' and ' Domain model' approach via the Options dialog, although we recommend using the new 'Domain Model' approach.
  
  Do get back in case you need further assistance.
