             *Similar to using [DataType(DataType.EmailAddress)] attribute.*/
           .SetDataType(DataType.EmailAddress)

            /*Setting custom format for the field.
             *Similar to using [DisplayFormat(DataFormatString = "The email is : {0}")].*/
           .SetDisplayFormat("The email is : {0}")

            /*Setting display name.
             *Similar to using [Display(Name = "Email")] attribute.*/
           .SetDisplayName("Email")

        For(m => m.Password)
            //Setting display name from resources
           .SetDisplayName(Account.UserPasswordLabel) 
           .SetDataType(DataType.Password)

        this.For(m => m.Phone)

             //Phone field will be editable only when current user is in the specific role
            .SetReadOnly(() => !Thread.CurrentPrincipal.IsInRole("AllowEditPhone"))

            //Displays the number in the following format original 123456789 => transformed: 123***789
            .ApplyValueTransform(s => Regex.Replace(s, @"(?<=\d{3})\d(?=\d{3})", "*", RegexOptions.Compiled));
    }
}

Conditional Annotations

Used to apply annotations conditionally based on result of predicate:

The following code will make Phoneproperty read only, in case that AllowEditPhone property is set to false

 this.When(model => !model.AllowEditPhone,
 () => {
     this.For(m => m.Phone).SetReadOnly(false);
 });
