I've only recently updated to VS 2013 and when using an MVC 3 app I'm experiencing an auto formatting issue whereby the model declaration at the top of a cshtml file is set to lowercase when using the CTRL K + D shortcut (or highlight all, Format Selection) e.g.
@model IEnumerable<Review>
CTRL K + D
@model IEnumerable<review>
Same project in VS 2012 works perfectly ok and auto formatting works so I tried export those settings and importing them but without any luck.
I've tried looking in Tools - Options - Text Editor amd changed the Client Tag in html web forms to 'As entered' but that also hasn't worked.
