title: Referencing Silverlight UI Automation Helper dll in CodedUI Test
body: <p>I am trying to automate a Silverlight web application using CodedUI. The application under test is already developed and deployed in our testing environment.</p>
  
  <p>I tried automating using record feature of CodedUI but was unsuccessful in getting the recorded actions. On googling, I found that I have to install this plugin: <a href="https://visualstudiogallery.msdn.microsoft.com/28312a61-9451-451a-990c-c9929b751eb4" rel="nofollow">https://visualstudiogallery.msdn.microsoft.com/28312a61-9451-451a-990c-c9929b751eb4</a></p>
  
  <p>I did the installation and still was unable to record. Then I found that I have to reference Microsoft.VisualStudio.TestTools.UITest.Extension.SilverlightUIAutomationHelper.dll file in the Silverlight project.</p>
  
  <p>This is where I am stuck. I am not sure whether to reference this file in :</p>
  
  <ol>
  <li>The project which was used to develop the Silverlight application</li>
  <li>The CodedUI test project.</li>
  </ol>
  
  <p>If it is option 1, I don't have access to the development project. Is there any workaround for this ?  </p>
