Request Validator

If you want add validation to your request first thing you need to do is install fluent validation package

PM> Install-Package FluentValidation.AspNetCore

To use valdation on your request just use AddValidation method in your request, it should look something like this

public sealed partial record Query(string Id)
{
    public static void AddValidation(AbstractValidator<Query> v)
        => v.RuleFor(x => x.Id).NotEmpty();
}
