I need to place unique description and keywords meta tags to each page. Tried this. But its not clicking.
@{ ViewBag.Title = \"Title\"; ViewBag.Descr
You can do as you did, but you have to link them in your _Layout.cshtml. Add this to your _Layout.cshtml in the section:
@if(ViewBag.Description!=null) { } @if(ViewBag.Keywords!=null) { }
