Quickstart: Acquire a token and call Microsoft Graph in a .NET console app

We apologize for the inconvenience and appreciate your patience while we work to get this resolved.

Quickstart: Get a token and call the Microsoft Graph API by using a console app's identity

In this quickstart, you download and run a code sample that demonstrates how a .NET console application can get an access token to call the Microsoft Graph API and display a list of users in the directory. The code sample also demonstrates how a job or a Windows service can run with an application identity, instead of a user's identity. The sample console application in this quickstart is also a daemon application, so it's a confidential client application.


.NET 6.0 SDK

Download and configure your quickstart app

Step 1: Configure your application in the Azure portal

For the code sample in this quickstart to work, create a client secret and add the Graph API's User.Read.All application permission.

Already configured Your application is configured with these attributes.

Step 2: Download your Visual Studio project

Run the project by using Visual Studio 2019.


To avoid errors caused by path length limitations in Windows, we recommend extracting the archive or cloning the repository into a directory near the root of your drive.



If you try to run the application at this point, you'll receive an HTTP 403 - Forbidden error: "Insufficient privileges to complete the operation." This error happens because any app-only permission requires a Global Administrator of your directory to give consent to your application. Select one of the following options, depending on your role.

Global tenant administrator

If you're a Global Administrator, go to the API Permissions page and select Grant admin consent for Enter_the_Tenant_Name_Here.

Standard user

If you're a standard user of your tenant, ask a Global Administrator to grant admin consent for your application. To do this, give the following URL to your administrator:


You might see the error "AADSTS50011: No reply address is registered for the application" after you grant consent to the app by using the preceding URL. This error happens because this application and the URL don't have a redirect URI. You can ignore it.

Step 4: Run the application

If you're using Visual Studio or Visual Studio for Mac, press F5 to run the application. Otherwise, run the application via command prompt, console, or terminal:

Visual Studio for Mac is scheduled for retirement by August 31, 2024 in accordance with Microsoft’s Modern Lifecycle Policy. Visual Studio for Mac 17.6 will continue to be supported until August 31, 2024, with servicing updates for security issues and updated platforms from Apple. Refer to What's happening to Visual Studio for Mac for more information.

cd {ProjectFolder}\1-Call-MSGraph\daemon-console
dotnet run

In that code:

  • {ProjectFolder} is the folder where you extracted the .zip file. An example is C:\Azure-Samples\active-directory-dotnetcore-daemon-v2.

You should see a list of users in Microsoft Entra ID as result.

This quickstart application uses a client secret to identify itself as a confidential client. The client secret is added as a plain-text file to your project files. For security reasons, we recommend that you use a certificate instead of a client secret before considering the application as a production application. For more information on how to use a certificate, see these instructions in the GitHub repository for this sample.

More information

This section gives an overview of the code required to sign in users. This overview can be useful to understand how the > code works, what the main arguments are, and how to add sign-in to an existing .NET console application.

How the sample works

Diagram that shows how the sample app generated by this quickstart works.


Microsoft Authentication Library (MSAL, in the Microsoft.Identity.Client package) is the library that's used to sign in users and request tokens for accessing an API protected by the Microsoft identity platform. This quickstart requests tokens by using the application's own identity instead of delegated permissions. The authentication flow in this case is known as a client credentials OAuth flow. For more information on how to use MSAL.NET with a client credentials flow, see this article.

You can install MSAL.NET by running the following command in the Visual Studio Package Manager Console:

dotnet add package Microsoft.Identity.Client

MSAL initialization

You can add the reference for MSAL by adding the following code:

using Microsoft.Identity.Client;

Then, initialize MSAL by using the following code:

IConfidentialClientApplication app;
app = ConfidentialClientApplicationBuilder.Create(config.ClientId)
                                          .WithAuthority(new Uri(config.Authority))
Element Description
config.ClientSecret The client secret created for the application in the Azure portal.
config.ClientId The application (client) ID for the application registered in the Azure portal. You can find this value on the app's Overview page in the Azure portal.
config.Authority (Optional) The security token service (STS) endpoint for the user to authenticate. It's usually https://login.microsoftonline.com/{tenant} for the public cloud, where {tenant} is the name of your tenant or your tenant ID.

For more information, see the reference documentation for ConfidentialClientApplication.

Requesting tokens

To request a token by using the app's identity, use the AcquireTokenForClient method:

result = await app.AcquireTokenForClient(scopes)
Element Description
scopes Contains the requested scopes. For confidential clients, this value should use a format similar to {Application ID URI}/.default. This format indicates that the requested scopes are the ones that are statically defined in the app object set in the Azure portal. For Microsoft Graph, {Application ID URI} points to https://graph.microsoft.com. For custom web APIs, {Application ID URI} is defined in the Azure portal, under **Application Registration ** > Expose an API.

For more information, see the reference documentation for AcquireTokenForClient.
