You apply the ExcludeAttribute attribute to a property when you do not want to make the property available to client applications. Many values, such as identity values, are managed in the data source and do not need to be displayed or edited in the client.

The following example shows the ExcludeAttribute applied to property named rowguid which is of Guid type.

C#
VB
Copy 
[MetadataTypeAttribute(typeof(Address.AddressMetadata))]
public partial class Address
{

    internal sealed class AddressMetadata
    {
        // Metadata classes are not meant to be instantiated.
        private AddressMetadata()
        {
        }

        public int AddressID;

        [Required]
        [StringLength(60)]
        public string AddressLine1;

        public string AddressLine2;

        [Required]
        [StringLength(30)]
        public string City;

        public string CountryRegion;

        public EntityCollection<CustomerAddress> CustomerAddresses;

        public DateTime ModifiedDate;

        [Required]
        public string PostalCode;

        [Exclude]
        public Guid rowguid;

        public string StateProvince;
    }
}
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
