Browse with Edge IE compatibility

I have tried everything to debug my web applications under IE compatibility mode in Edge and launching in Visual Studio 2019 ignores any settings. I have added localhost (as well as port number) to Edge compatibily and applications will only run in Edge Native. We have a bunch of legacy applications that have no funding to run in native Edge mode so they will continue to run in IE compabilibilty. How do I debug my applications, and further develop, after IE is removed from my development PC?

    Hi @Brock, John ,

    How do I debug my applications, and further develop, after IE is removed from my development PC?

    Based on your description, I think the main problem is that you don't know how to debug in a page in Edge IE Mode. If this is the case, you can use IEChooser to open Internet Explorer DevTools, as follows:

    1. In Windows, open the Run dialog box. For example, press the 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.

    But if I have any misunderstands about this issue, please point it out, and please describe your problem more clearly, thanks for understanding.

    Regards,
    Xudong Peng
