Does anyone know why i cannot see the source code of a website while in Internet Explorer mode in Microsoft Edge?

I need to see the source code on a website that only works in Internet Explorer mode in Microsoft Edge. Whereas on Micrososft Edge you can see the source code by by pressing shift + ctrl + c, when I try doing that on Internet Explorer the source code is empty.

If I right click on the website in Internet Explorer and press "show source" I get this weird html script on Notepad instead of the popup interface. Can anyone help? Thank You!

Please note that pressing shift + ctrl + c calls out Edge Developer Tools, which only works in Microsoft Edge, not in Internet Explorer mode. That's why it won't show anything. Also, it is by design that right-clicking and then selecting View Source launches Notepad.

To view source code of IE mode pages, you should use a standalone developer tools for IE mode called IEChooser

1. In Windows, open the Run dialog. For example, press Windows logo key + R.
2. Enter %systemroot%\system32\f12\IEChooser.exe, and then click OK.
3. In IEChooser, select the entry for the IE mode tab.
