6- سپس برای Action به نام LogOn یک View میسازیم، برای Authenticate نیازی به ایجاد View ندارد چون قرار است درخواست کاربر را به آدرس دیگری Redirect کند. سپس کدهای زیر را برای View ایجاد شده وارد میکنیم.

پس از اجرای پروژه صفحه ای شبیه به پایین مشاهده کرده و سرویس دهنده OpenID خاص خود را میتوانید انتخاب نمایید.
7- برای فعال سازی عملیات احراز هویت توسط FormsAuthentication در سایت باید تنطیمات زیر را در فایل web.config انجام دهید.
<authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880" /> </authentication>

StructureMap 4.1 منتشر شد
- The assembly discovery mechanism in type scanning has new methods to scan for “.exe” files as Assembly candidates. I had removed “.exe” file searching in 4.0 thinking that it was more problematic than helpful, then several users asked for it back.
- The assembly discovery handles the PrivateBinPath of the AppDomain in all (known) cases now
- Child container creation is thread safe now
