After creating UserManager instance, you need to assign the passwordhasher property to your CustomPasswordHasher.
UserManager<ApplicationUser> UserManager = new UserManager<ApplicationUser>(store);
UserManager.PasswordHasher = new CustomPasswordHasher();
"CustomPasswordHasher" Class should implement "IPasswordHasher" interface
you can see example here
