Office 365 SDK Docs - Add Details on How To Authenticate
This guidance (http://msdn.microsoft.com/en-us/office/office365/howto/common-calendar-tasks-client-library#GetAuthToken) is not as complete as it should be. You likely want to add add additional NuGet packages to make this work. Suggest adding the recommended way to authenticate, such as OWIN / ADAL, to help people get started faster.
We’ll include this as part of our next round of documentation improvements.
