      -  View - refers to all elements displayed by the GUI;
      -  ViewModel - an abstraction of the View that also serves in data binding between the View and the Model;

  When I try and open the NorthwindApplication.xaml file I get the following errors
  Error 3 The type 'Model.Category' cannot be used as type parameter 'TEntity' in the generic type or method 'ViewModel.Repository<TEntity>'. There is no implicit reference conversion from 'Model.Category' to 'Telerik.OpenAccess.SPI.dataobjects.PersistenceCapable'. C:\Users\THamaluk\Downloads\Telerik\OpenAccess\wpfmvvmusingopenaccess\ViewModel\CategoryViewModel.cs 22 54 ViewModel
   
  the code that causes these errors is
  

   

   

  public CategoryViewModel()

   

  {

   

  this.repositoryCategory = new Repository<Category>();

   

   

  this.repositoryProduct = new Repository<Product>();

   

   

  this.Load();

   

  }
  with "Category" and "Product" causing the above error. Can you please help me correct these errors ?

  Hello Telerik Admin,
  
  You could download the Telerik OpenAccess SDK(blog post) that we introduced in Q3. The SDK browser ships rich set of examples including implementation of Silverlight application using MVVM.
  You could find it from your account under the download section.
  Hope that helps.

  I was able to download, build and run this sample, however is there any documentation that explains how it works ?
  
  Are there any other ORM and WPF MVVM samples ?

  Hi Telerik Admin,
  
  1.    Currently we do not provide documentation about the examples shipped with the Telerik OpenAccess SDK.
  2.    You could find this help section useful. It demonstrates how to use Telerik OpenAccess ORM with WPF.
  If any other question arise please contact us back.
