Steps to reproduce

  1. Create a .NET Win Forms UserControl that displays something simple (for example the current date/time). Build to a DLL.
  2. Create a simple HTML page that embeds this control - sample below.
  3. Configure IIS to serve the page from a URL (local or other)
  4. Configure CASPOL and EnableIEHosting registry settings to allow .NET controls to run when embedded in web page
  5. Browse to the page using IE11 on Win10 (1607) - fails to display the control. Use dev tools to force to IE8 mode - successfully displays. It also works on Win7/IE11 without IE8 mode.

Sample HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<body>
  <object id="testControl" classid="TestControlLibrary.dll#TestControlLibrary.TestControl" style="width: 300px; height: 100px"></object>
  <br/>
  <input type="button" onclick="alert(document.all.testControl.Test())" value="Test" />
</body>
</html>

    Thank you for your
    feedback and sorry to hear that you are having difficulties with Internet
    Explorer. However we’re not presently working on feature bugs in Internet
    Explorer outside of security-related issues.

    Alternatively, if
    you have a premier support contract you can visit
    https://premier.microsoft.com

    and open
    a support incident and work with an engineer to address this issue.

     

    Best regards,

    The MS Edge Team
