when I work in debug with IIS Express in visual studio and try to reach a file in /wwwroot, I don't have any problem with the path = 'wwwroot/fileName'.
But when I deploy my website into IIS Express server, I can't reach the file anymore and I get error because the file doesn't exist.
Did I make something wrong ? Did the path is not the same when WebSite is deploy ?
PS : The file is '.xlsx' extension
