{
     [Required(ErrorMessage =Resources.PageResources.enterYourEmail)]
     public String Email{ get; set; }

     [Required(ErrorMessage =Resources.PageResources.enterPassword)]

Try this

 [Required(ErrorMessageResourceType = typeof(Resources.Resources),       
            ErrorMessageResourceName = "enterYourEmail")]
 public String Email{ get; set; }

 [Required(ErrorMessageResourceType = typeof(Resources.Resources),       
            ErrorMessageResourceName = "enterPassword")]
 public String Password { get; set;

I had to add ErrorMessage = null to make it work with asp.net mvc 5. Like: [Compare("NewPassword", ErrorMessageResourceType = typeof (Resources.ModelStateErrors.Index), ErrorMessageResourceName = "passworddonotmatch", ErrorMessage = null)] public string ConfirmPassword { get; set; }

A similar approach but without the problem related by @Ali Baig about to have to add ErrorMessage = null to make it work.

    [Required(ErrorMessageResourceName = nameof(Resources.Global_Errors.ReqName),
 ErrorMessageResourceType = typeof(Resources.Global_Errors))]
