Silverlight4: navigation wizard

I want to make a wizard in Silverlight 4. How to get started?

Let's say I want 4 screens with choices and with a "next" and "previous" button. After the 4 screens, I want to show the 开发者_运维技巧"actual" application/mainpage based on the choices the user made in the wizard. On that page there must be an option to return to the first page of the wizard again.

WizardPage1.xaml -> Next -> WizardPage2.xaml -> Next -> WizardPage3.xaml -> Next -> WizardPage4.xaml -> Finish -> MainPage.xaml -> Back to start -> WizardPage1.xaml ->...

Can I use the navigation framework as solution? Users are not allowed to directly navigate to the mainpage. Or do I have to use a "containerpage" with a contentcontrol for the wizard steps? But how to navigate away from containerpage to the mainpage?

Thanks for your suggestions.
