How can I create a RuleSet with a .NET FluentValidation InlineValidator?

Question

I'm creating an InlineValidator (from the FluentValidation nuget package/library).

var validator = new InlineValidator<Person>;
validator.RuleFor(x => x.Surname).NotNull();
validator.RuleSet("someRuleSet", () => {
    // ?????
            });

When I try to call the RuleSet method in there, it seems to not compile.

How can I create a RuleSet against an InlineValidator please ?

Here's the example ruleset i'm trying...

.RuleSet("someRuleSet", () =>
{
    RuleFor(x => x.Name).NotNull();
    RuleFor(x => x.Age).NotEqual(0);
}

You can't access RuleFor as a global method, it sits on the InlineValidator. Here's an example of how you can add a RuleSet and then validate against it:

// Setup the inline validator and ruleset
var validator = new InlineValidator<Person>();

validator.RuleSet("test", () =>
{
    validator.RuleFor(x => x.Name).NotNull();
    validator.RuleFor(x => x.Age).NotEqual(0);
});

var person = new Person();

// Validate against the RuleSet specified above
var validationResult = validator.Validate(person, ruleSet: "test");    

Console.WriteLine(validationResult .IsValid); // Prints False

For those who are using FluentValidation version 10.0 or above, according to the 10.0 Upgrade Guide, the Validation/ValidationAsync extension methods with the ruleSet argument which is a string type had been removed.

validator.Validate(instance, ruleSet: "someRuleSet");

// For multiple rule sets
// validator.Validate(instance, ruleSet: "someRuleSet,AnotherRuleSet");

The migration to be taken is by providing the Action<ValidationStrategy<T>> instance by defining the rule sets as the second argument:

validator.Validate(instance, v => 
{
    v.IncludeRuleSets("someRuleSet");

    // For multiple rule sets
    // v.IncludeRuleSets("someRuleSet", "AnotherRuleSet");
});
