3. Mastering Office 365 Development
Cloud First! In this session we will show you how you can extend
your Office 365 solutions with Development. We will go through
identity management as well as showing you how you can use
client libraries and build in some cool Office 365 functionality in
your own solutions. We will also use the Office 365 API to develop
our own Windows 8.1 app.
