I replied to your question in the other forum thread you have started. Below is the answer I gave you there:
"Have you tried using the Telerik.VisualStudio.TestTools.UITest.Extension.ExtensionsCore assembly along with your test project? It is located under "C:\Program Files (x86)\Telerik\UI for WPF Q2 2014\Binaries\WPF40\TestTools\VS2012". Also copy the DLL to "C:\Program Files (x86)\Common Files\Microsoft Shared\VSTT\11.0" in case you are using VS 2012.
More information about the UI Automation support can be found here."
I would suggest to keep the conversation in a single thread so it is easier for both sides to follow.
Hope this helps.
