No Silverlight controls were detected

Asked By 30 points N/A Posted on -

Hi Tech savvy,

I have Microsoft Visual studio package in the system and I download and install it from the authorized website. While I try to perform some action, I keep getting this error message. How do I fix this error? I tried to run the update even then I get this error message. I have a doubt whether some files are corrupted while download. Please suggest me some solution. Thanks.


No Silverlight controls were detected. Verify that the application under test is built using Silverlight assemblies with a version of 4.0 or greater and that a reference to the Microsoft.VisualStudio. TestTools.UITest.Extension.SilverlightUIAutomationHelper.dll assembly has been added to the project. For more information, see

In order to get rid of this issue, you have to make Internet Explorer to be run on Compatibility mode.

  1. Open Internet Explorer.
  2. Open your Silverlight Application.
  3. Beside the URL box, click the “Compatibility Mode” button.
  4. Now, re-run the Coded UI Builder. This should work fine.

Also, you can fix this issue by adding “Microsoft.VisualStudio.TestTools.UITest.Extension.SilverlightUIAutomationHelper.dll” to your Silverlight application. This will help the program to get the assembly and run smoothly.
