This sample shows how to connect an ASP.NET 4.6 MVC web app to a Microsoft work or school (Azure Active Directory) or personal (Microsoft) account using the Microsoft Graph API to retrieve a user's profile picture, upload the picture to OneDrive, and send an email that contains the photo as an attachment and the sharing link in its text. It uses the Microsoft Graph .NET Client Library to work with data returned by Microsoft Graph.

In addition, the sample uses the Microsoft Authentication Library (MSAL) for authentication. The MSAL SDK provides features for working with the Azure AD v2.0 endpoint, which enables developers to write a single code flow that handles authentication for both work or school (Azure Active Directory) and personal (Microsoft) accounts.

Important Note about the MSAL Preview

This library is suitable for use in a production environment. We provide the same production level support for this library as we do our current production libraries. During the preview we may make changes to the API, internal cache format, and other mechanisms of this library, which you will be required to take along with bug fixes or feature improvements. This may impact your application. For instance, a change to the cache format may impact your users, such as requiring them to sign in again. An API change may require you to update your code. When we provide the General Availability release we will require you to update to the General Availability version within six months, as applications written using a preview version of library may no longer work.

Prerequisites

This sample requires the following:

• Visual Studio 2015
• Either a Microsoft account or Office 365 for business account. You can sign up for an Office 365 Developer subscription that includes the resources that you need to start building Office 365 apps.

Register the application

1. Sign into the App Registration Portal using either your personal or work or school account.

2. Choose Add an app.

3. Enter a name for the app, and choose Create application.

   The registration page displays, listing the properties of your app.

4. Copy the Application Id. This is the unique identifier for your app.

5. Under Application Secrets, choose Generate New Password. Copy the password from the New password generated dialog.

   You'll use the application ID and password to configure the sample app in the next section.

6. Under Platforms, choose Add platform.

7. Choose Web.

8. Make sure the Allow Implicit Flow check box is selected, and enter http://localhost:55065/ as the Redirect URI.

   The Allow Implicit Flow option enables the hybrid flow. During authentication, this enables the app to receive both sign-in info (the id_token) and artifacts (in this case, an authorization code) that the app can use to obtain an access token.

9. Choose Save.

Build and run the sample

1. Download or clone the Microsoft Graph Connect Sample for ASP.NET 4.6.

2. Open the sample solution in Visual Studio.

3. In the Web.config file in the root directory, replace the ida:AppId and ida:AppSecret placeholder values with the application ID and password that you copied during app registration.

4. Press F5 to build and run the sample. This will restore NuGet package dependencies and open the app.

   If you see any errors while installing packages, make sure the local path where you placed the solution is not too long/deep. Moving the solution closer to the root of your drive resolves this issue.

5. Sign in with your personal or work or school account and grant the requested permissions.

6. Choose the Get email address button. When the operation completes, the email address of the signed-in user is displayed on the page.

7. Optionally edit the recipient list and email subject, and then choose the Send email button. When the mail is sent, a Success message is displayed below the button.

8. Next steps: Check out the Microsoft Graph Snippets Sample for ASP.NET 4.6 to see examples of common Microsoft Graph operations.

Code of note

Note: To understand the code for calling the Microsoft Graph API in an ASP.NET MVC app, see Get started with Microsoft Graph in an ASP.NET 4.6 MVC app.

• Startup.Auth.cs. Authenticates the current user and initializes the sample's token cache.

• SessionTokenCache.cs. Stores the user's token information. You can replace this with your own custom token cache. Learn more in Caching access tokens in a multitenant application.

• SampleAuthProvider.cs. Implements the local IAuthProvider interface, and gets an access token by using the MSAL AcquireTokenSilentAsync method. You can replace this with your own authentication provider.

• SDKHelper.cs. Initializes the GraphServiceClient from the Microsoft Graph .NET Client Library that's used to interact with the Microsoft Graph.

• HomeController.cs. Contains methods that use the GraphServiceClient to build and send calls to the Microsoft Graph service and to process the response.

  • The GetMyEmailAddress action gets the email address of the current user from the mail or userPrincipalName property.
  • The SendMail action sends an email on behalf of the current user.

• Graph.cshtml. Contains the sample's UI.
