This thing is the bane of my existence, I hate it with all my heart.Two Approaches I've seen here did not work for me:[*]In the properties pages of the web application, go to Web tab and choose 'Use Local IIS Server'[*]In the other properties (F4 on Project), set 'Always Start When Debugging' to false.Still, when I attach my web application to the IIS process, it automatically starts the Dev server. If I use F5 to start my project, it always uses the Dev server. This seems to happen every few months, where I'm simply unable to kill the Dev server in favor of IIS. Is there any way to just get rid of the thing? I don't see why it exists, and in my experience it's nearly impossible to debug with.Edit: I do indeed have IIS, I use it constantly. I know my vDirs are all setup correctly, etc. It seems like something is completely overriding my settings to use IIS. Would manually deleting everything having to do with the dev server cause major issues? I'd rather see cryptic OS file not found messages than see that damn server pop up one more time.
