How to use rulesets with ValidateAsync in FluentValidation's world?

Question

I'd like to use ruleSets with my FluentValidation classes when I call validateAsync, but I haven't found anything about it in the documentation, which provides examples for validate only, nor in issues of the project github repo.

With rulesets I can keep my validation rules in the same class, without rulesets I need to create validation classes for every case where I need validation for the same class.

What is the solution for this? If there is no ruleSet parameter for ValidateAsync what is the reason?

ValidateAsync does have a ruleSet parameter. For it to be available you need to add the FluentValidation namespace:

using FluentValidation;

Usage is like the regular (synchronous) Validate:

var validationResult = await validator.ValidateAsync(account, ruleSet: "nameOfRuleSet");

In library Fluent validation 10 onwards.

using FluentValidation;
var validationResult = await 
validator.ValidateAsync(account,options=>options("nameOfRuleSet"));

In 10 versions and above

await validator.ValidateAsync(account, options => options.IncludeRuleSets("default","update"),cancellationToken);

Without a cancellation token

await validator.ValidateAsync(account, options => options.IncludeRuleSets("default","update"));

Where an update is a new ruleSet in a validator

 RuleSet("update",
    () => {
     ...
     ...
  });
