Loading Web Project in VS2015 — no styling or images
问题 So I just moved an existing web project over to Visual Studio 2015 Community Edition which I had started back in VS2013 Ultimate and upon running it in the browser all of the styling was missing and no images were showing up. All of the content worked however and I could navigate the site, until I tried to open a picture and I got the error: HTTP Error 500.19 - Internal Server Error Config Error Cannot add duplicate collection entry of type 'mimeMap' with unique key attribute 'fileExtension'
