This sample shows how to connect and use Microsoft Graph (previously called Office 365 unified API) using the a pre-release of the Microsoft Graph client library. It uses Active Directory Authentication Library to acquire OAuth2 tokens to call the Microsoft Graph. This console app can operate in 2 modes: in the traditional delegated user mode (aka app+user mode), and/or in application mode (where no user sign in is required and the app accesses the API as itself).

To use this sample, you need the following:

• Visual Studio 2013 or 2015 installed and working on your development computer.

• An Office 365 account. You can sign up for an Office 365 Developer subscription that includes the resources that you need to start building Office 365 apps.

  Note: If you already have a subscription, the previous link sends you to a page with the message Sorry, you can’t add that to your current account. In that case use an account from your current Office 365 subscription.

• A Microsoft Azure tenant to register your application. Azure Active Directory (AD) provides identity services that applications use for authentication and authorization. A trial subscription can be acquired here: Microsoft Azure.

  Important: You also need to make sure your Azure subscription is bound to your Office 365 tenant. To do this, see the Active Directory team's blog post, Creating and Managing Multiple Windows Azure Active Directories. The section Adding a new directory will explain how to do this. You can also see Set up your Office 365 development environment and the section Associate your Office 365 account with Azure AD to create and manage apps for more information.

• You'll need to register 2 applications in Azure:

  1. The client ID and redirect URI values of a native client application registered in Azure, for the delegated user mode. This application must be granted the NEED TO GET THE LIST OF PERMS Send mail as signed-in user permission for the Microsoft Graph. Add a web application in Azure and grant the proper permissions to it.
  2. The client ID and secret of a web application also registered in Azure, for the application mode.
  3. You'll also need the tenant ID for the tenant you are registering these applications in.

1. Open NewName file.
2. In Solution Explorer, open the Constants.cs file.
3. Follow the instructions in the Constants.cs file to populate the properties for the 2 apps.
