Inconsistency with Url.Content("~")

[Daniel15]

In previous versions of ASP.NET MVC, Url.Content("~") returns the application's root directory (ie. /foo). On ASP.NET MVC 6, this just returns a verbatim "", and you need to actually use Url.Content("~/"). It's a subtle difference, but it appears that older versions just check that the first character is "", whereas newer versions check that the string starts with "~/" (ie. it contains a tilde and a slash)

Old code:

bool isAppRelative = contentPath[0] == '~';

New code:

if (path.StartsWith("~/", StringComparison.Ordinal))
