Could you be more specific where are you searching for the WPF samples, and on which on the following steps do you have a problem:
1) Go to Start Menu -> All Programs -> Telerik -> OpenAccess ORM -> OpenAccess SDK Browser
2) From the top left tabs, choose second one "Samples".
3) In this tab, you should see two panels one above the other. The top one has a bottom bar with "Show/Hide navigation" and "Samples cache settings". If you see "Show Navigation" click on it, to see a navigation panel.
4) From the top left list, choose WPF (it is the last row). On the right list you will see all examples presenting how to use OpenAccess ORM with a WPF user interface, in C# and/or Visual Basic. You can start a sample directly or open it in Visual Studio.
In addition, I would recommend you to install the brand new release of Telerik OpenAccess SDK - Q3 2012 SP1. You can download it from here
