What is the best way to add attributes to auto-generated entities (using VS2010 and EF4)

List<ValidationResult> errorList = new List<ValidationResult>();

        bool bValid = client.IsValid<Client, ClientMetadata>(ref errorList, false);

 

 

    public static bool IsValid<T, U>(this T obj, ref List<ValidationResult> errors, bool validateAllProperties = true) where T : IValidatableObject

    {

        //If metadata class type has been passed in that's different from the class to be validated, register the association

        if (typeof(T) != typeof(U))

        {

            TypeDescriptor.AddProviderTransparent(new AssociatedMetadataTypeTypeDescriptionProvider(typeof(T), typeof(U)), typeof(T));

        }

 

        var validationContext = new ValidationContext(obj, null, null);

        var validationResults = new List<ValidationResult>();

        Validator.TryValidateObject(obj, validationContext, validationResults, validateAllProperties);

 

        errors = validationResults;

 

        if (validationResults.Count > 0)

            return false;

        else

            return true;

    }
