  using System.ComponentModel.DataAnnotations;




  namespace yplaylist.Models
  {
     [MatadataType(typeof(Song_Validation))]
     public partial class Song
     {

     }

     public class Song_Validation
     {



     }
 }

MetadataType is highlighted saying that it could not be found missing a using directive or assembly reference? what am I missing?

Answer 1

I’m not sure if you copied your code directly into your question, but you have a spelling error in your code:

It should be:

[MetadataType(typeof(Song_Validation))]
public partial class Song
{ 
}

You spelled it as MatadataType.
