Why am I unable to Debug my ASP.NET website in Visual Studio?

Question

I used to be able to attach to my w3wp process and Debug my web application, but this is not working anymore. I have no idea what changed to break this. I\'m using Visual St

Answer 1

I faced the same issue. The w3wp process took a lot of memory and did not want to be reset on web application publishing.

Press Ctrl+Alt+Delete > Go to "Processes" tab > find w3wp process and kill it. Run the app again (if this is an mvc app, just go to a related url to automatically recreate w3wp process).

Warnings will disappear after that.
