FluentValidation Call RuleSet and Common Rules

I have the following class

public class ValidProjectHeader : AbstractValidator<Projects.ProjectHeader>
    {
        public ValidProjectHeader()
        {

            RuleFor(x => x.LobId).Must(ValidateLOBIDExists);
            RuleFor(x => x.CreatedByUserId).NotEmpty();
            RuleFor(x => x.ProjectManagerId).NotEmpty();
            RuleFor(x => x.ProjectName).NotEmpty();
            RuleFor(x => x.SalesRepId).NotEmpty();
            RuleFor(x => x.DeliveryDate).NotEmpty();
            RuleFor(x => x.ProjectStatusId).NotEmpty();
            RuleFor(x => x.DeptartmentId).NotEmpty();
            RuleFor(x => x.CustomerId).NotEmpty();

            RuleSet("Insert", () =>
            {
                RuleFor(x => x.ProjectLines).Must(ValidateProjectLines).SetCollectionValidator(new ValidProjectLine());
            });
            RuleSet("Update", () =>
            {
                RuleFor(x => x.ProjectLines).SetCollectionValidator(new ValidProjectLine());
            });


        }

and what i am trying to do is call the validation with the rulset but i also want to return the "common" rules when i call the validation with the RuleSet.

the Code I have for calling the validation is as follows

public abstract class BaseValidator
    {
        private List<ValidationFailure> _errors;
        public bool IsValid { get; protected set; }
        public List<ValidationFailure> Errors
        {
            get { return _errors; }
            protected set { _errors = value; }
        }
        public virtual bool CallValidation()
        {
            Errors = new List<ValidationFailure>();
            ValidatorAttribute val = this.GetType().GetCustomAttributes(typeof(ValidatorAttribute), true)[0] as ValidatorAttribute;
            IValidator validator = Activator.CreateInstance(val.ValidatorType) as IValidator;
            FluentValidation.Results.ValidationResult result = validator.Validate(this);
            IsValid = result.IsValid;
            Errors = result.Errors.ToList();
            return result.IsValid;
        }

        public virtual bool CallValidation(string ruleSet)
        {
            Errors = new List<ValidationFailure>();
            ValidatorAttribute val = this.GetType().GetCustomAttributes(typeof(ValidatorAttribute), true)[0] as ValidatorAttribute;
            IValidator validator = Activator.CreateInstance(val.ValidatorType) as IValidator;
            FluentValidation.Results.ValidationResult result = validator.Validate(new FluentValidation.ValidationContext(this, new PropertyChain(), new RulesetValidatorSelector(ruleSet)));
            IsValid = result.IsValid;
            Errors = result.Errors.ToList();
            return result.IsValid;
        }

        public BaseValidator()
        {
            Errors = new List<ValidationFailure>();
        }
    }

I can call the Method CallValidation with the member ruleSet but it is not calling the "common" rules also.

I know I can create a "Common" RuleSet for running these rules but in that case i would have to call the validation with the Common RuleSet always.

Is there any way I can call the RuleSet and also call the common rules.

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<T>, which doesn't have a ruleSet argument.
