Vytvoreni uzivatele pomoci UserManager, nepochopeni pouziti DI

Ahoj,

chtel bych si vytvorit v databazi „prvniho“ uzivatele, ale nedari se mi nijak ziskat vytvorenou tridu UserManager, na te tride jsem nic nemenil stejne tak jako na configu. Uz jsem z toho docela zoufaly z tehle nove 2.1 verzne nette, vsude jen ctu v dokumentaci jak je DI uzasne atd., ale nikde neni zadny konkretni priklad jak to pouzivat :/ Mohl by mi prosim nekdo poradit ?

Config.neon vypada takto
