c# comment "//" on razor view cannot be ignored

[johnsonckcow]

for example, when there are c# comment "//" in .cshtml file, the output will become 1 line and all will be commented
@{
//ViewBag.Title = "Form Detail";
ViewBag.Title = @Resources.Global.FORM_DETAIL + "(" + @Resources.Global.SNAPSHOT +")";
}

->
@{ //ViewBag.Title = "Form Detail"; ViewBag.Title = @Resources.Global.FORM_DETAIL + "(" + @Resources.Global.SNAPSHOT +")"; }
