FluentValidation Call RuleSet and Common Rules

Question

I have the following class

public class ValidProjectHeader : AbstractValidator
    {
        public ValidProjectHeader()
        {         


        

Answer 1

Instead you could do this:

using FluentValidation;
...
FluentValidation.Results.ValidationResult resultCommon =
    validator.Validate(parameter, ruleSet: "default, Insert");

The using directive is required to bring the Validate() extension method from DefaultValidatorExtensions into scope, which has the ruleSet property. Otherwise you will only have the Validate() method available from inheriting AbstractValidator, which doesn't have a ruleSet argument.
