I am getting this error whenever I try to debug my project from visual studio.
I tried adding these settings to launchSettings.json but still no difference.
I found two processes in the task manager running "Internet Explorer" with the good old IE-Icon. After killing them, debugging was working again. I also closed all Chrome-Processes. I am not sure if that is related, but I doubt it because I already tried that in the past.
FYI for anyone having this issue, I just discovered on my system that Apple has a new iCloud Service that is using the default port 1692 for IIS Express in my project. I am looking into how to change the port in Visual Studio 2017.
Make sure to disable JavaScript debugging.
I've seen this error if I don't run Visual Studio as an Administrator.
If you're not already doing so, right-click the VS icon in the start tray, right click your version of Visual Studio from the pop-up, and select "Run as administrator." Then load and run your project.
