Connecting to Office 365 is the first step every app must take to start working with Office 365 services and data. This sample shows how to connect and use Office 365 unified API (preview) to send an email. It uses Active Directory Authentication Library to make OAuth2 call.
Note: To understand the code for calling the Office 365 unified API in an ASP.NET MVC app, see [Understanding Connect code sample] (https://github.com/OfficeDev/O365-AspNetMVC-Unified-API-Connect/wiki/Understanding-Connect-code-sample).
To use the Office 365 ASP.NET MVC Connect sample, you need the following:
-
Visual Studio 2015 installed and working on your development computer.
Note: This sample is written using Visual Studio 2015. If you're using Visual Studio 2013, make sure to change the compiler language version to 5 in the Web.config file: compilerOptions="/langversion:5
-
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.
-
A client ID and redirect URI values of an application registered in Azure. This sample application must be granted the Send mail as signed-in user permission for the Office 365 unified API (preview). Add a web application in Azure and grant the proper permissions to it.
Note: During the app registration process, make sure to specify http://localhost:55065 as the Sign-on URL.
-
Open UnifiedApiConnect.sln file.
-
In Solution Explorer, open the Web.config file.
-
Replace {your_app_client_ID} with the client ID of your registered Azure application.
-
Replace {your_app_client_secret} with the key of your registered Azure application.
-
Press F5 to build and debug. Run the solution and sign in to Office 365 with your organizational account.
Note: Copy and paste the start page URL address http://localhost:55065/home/index, to a different browser if you get the following error during sign in:AADSTS70001: Application with identifier ad533dcf-ccad-469a-abed-acd1c8cc0d7d was not found in the directory.
