Getting started

  • Artigo

To get started using Graph data in your application, you'll first need to enable authentication.

Set the global authentication provider

Authenticate with MSAL

Leverage the official Microsoft Authentication Library (MSAL) to enable authentication in NetStandard 2.0 applications using MsalProvider.

  1. Register your app in Azure AAD

    Before requesting data from Microsoft Graph, you will need to register your application to get a ClientID.

    After finishing the initial registration page, you will also need to add an additional redirect URI. Click on "Add a Redirect URI", then "Add a platform", and then on "Mobile and desktop applications". Check the https://login.microsoftonline.com/common/oauth2/nativeclient checkbox on that page. Then click "Configure".

  2. Install the CommunityToolkit.Authentication.Msal package.

  3. Set the ProviderManager.GlobalProvider to a new instance of MsalProvider with clientId and pre-configured scopes:

    using CommunityToolkit.Authentication;

string clientId = "YOUR-CLIENT-ID-HERE";
string[] scopes = new string[] { "User.Read" };

ProviderManager.Instance.GlobalProvider = new MsalProvider(clientId, scopes);

Note: Use the Scopes property to preemptively request permissions from the user of your app for data your app needs to access from Microsoft Graph.

Authenticate with WindowsProvider

Try out the WindowsProvider to enable authentication based on the native Windows Account Manager (WAM) APIs in your UWP apps, without requiring a dependency on MSAL.

  1. Associate your app with the Microsoft Store. The app association will act as our minimal app registration for authenticating consumer MSAs. See WindowsProvider for more details.

  2. Install the CommunityToolkit.Authentication.Uwp package

  3. Set the ProviderManager.GlobalProvider to a new instance of WindowsProvider with pre-configured scopes:

    using CommunityToolkit.Authentication;

string[] scopes = new string[] { "User.Read" };

ProviderManager.Instance.GlobalProvider = new WindowsProvider(scopes);

Sign in a user

Call SignInAsync to initiate the login process. This will prompt the user to specify an account or provide credentials.

using CommunityToolkit.Authentication;

await ProviderManager.Instance.GlobalProvider.SignInAsync();

You can also use the LoginButton control in UWP XAML apps to support the full sign in/out lifecycle and even display the user's photo and name when signed in.

<Grid xmlns:controls="using:CommunityToolkit.Graph.Uwp.Controls">
    <controls:LoginButton />
</Grid>

Make a Graph call

Once you are authenticated, you can then make requests to the Graph using the GraphServiceClient instance via extensions.

Install the CommunityToolkit.Graph package.

using CommunityToolkit.Authentication;
using CommunityToolkit.Graph.Extensions;

ProviderManager.Instance.ProviderStateChanged += (s, e)
{
    IProvider provider = ProviderManager.Instance.GlobalProvider;
    if (provider?.State == ProviderState.SignedIn)
    {
        var graphClient = provider.GetClient();
        var me = await graphClient.Me.Request().GetAsync();
    }
}
