Validation Rule: At least one property is required

Today i stump again upon the same problem . I wanted to throw a validation exception only if both of my properties do not have value. So lets create a validation rule for this one. More info on how we create custom validation rules can be found here Validation Module Since we are talking about multiple property values i think we should go with an attribute that is applied to a class and not to a property. Ok first we have to define that both our RuleBaseAttribute and RuleBaseProperties derived classes will implement . public interface IRuleRequiredForAtLeast1PropertyProperties { string MessageTemplateMustNotBeEmpty { get; set; } string Delimiters { get; set; } string TargetProperties { get; set; } } ok that looks nice lets explain what we have here for a bit.
