    {
      

         $builder = new AnnotationBuilder();
         $form    = $builder->createForm(User::class);
         
        return new ViewModel();
    }

 * @Annotation\Hydrator("Laminas\Hydrator\ObjectProperty")
 */
class User
{
    /**
     * @Annotation\Exclude()
     */
    public $id;

    /**
     * @Annotation\Filter({"name":"StringTrim"})
     * @Annotation\Validator({"name":"StringLength", "options":{"min":1, "max":25}})
     * @Annotation\Validator({"name":"Regex","options":{"pattern":"/^[a-zA-Z][a-zA-Z0-9_-]{0,24}$/"}})
     * @Annotation\Attributes({"type":"text"})
     * @Annotation\Options({"label":"Username:"})

Thank you for your support .

Answer 1

did you check the existence of AnnotationManager in your vendor? It should be under vendor/laminas/laminas-code/src/Annotation/AnnotationManager.php

Like you can see, it's located in a seperate package called laminas/laminas-code. Depending on your composer require statements it is not loaded by default.

Do you have any output with composer why laminas/laminas-code
