Run coded ui test of wpf application in MTM with build? - interactive window

I am trying to run coded UI test in MTM when build triggered in TFS 2015. set up is done with test agent and test controller and created Lab Environment. When I trigger build then build is success but test case is not executed showing below error ... Enabled interactive window in test agent as well.

CodedUITestMethod1 failed. Error calling Initialization method for test class CodedUITestProject1.CodedUITest1: Microsoft.VisualStudio.TestTools.UITest.Extension.UITestException: To run tests that interact with the desktop, you must set up the test agent to run as an interactive process. For more information, see "How to: Set Up Your Test Agent to Run Tests That Interact with the Desktop" (http://ift.tt/1nm26GO) If you are running the tests as part of your team build, you must also set up the build age

Pls suggest...

Thanks in advance
