Hello,
Thank you for your post.
There are several documentations on Authentication by Azure Active Directory.
You could start with a
Step-by-Step Guide of Azure AD and Multi-Factor Authentication. And the
Azure Active Directory documentation.
You also might want to look into the different
Authentication Scenarios for Azure AD.
There are several ready to use applications
Active Directory Marketplace.
However, since you are creating a Win8 App, you also might need the
Register you App with Azure AD.

Neelesh.
