Universal Windows Platform application signing in users with Microsoft and calling the Microsoft Graph
This simple sample demonstrates how to use the Microsoft Authentication Library (MSAL) for .NET to get an access token and call the Microsoft Graph (using OAuth 2.0 against the Azure AD v2.0 endpoint) for a Universal Windows Platform (UWP) application.
Steps to run
You can get full explaination about this sample, and build it from scratch by going to Windows desktop .NET guided walkthrough. You would have to change a few things (see below, build from scratch)
If you just want to quickly run it, use the following instructions:
Register an Azure AD v2.0 (converged) app.
- Navigate to the App Registration Portal.
- Go to the the
My Appspage, click
Add an App, and name your app.
- Set a platform by clicking
Add Platform, select
- Copy to the clipboard your Application Id
Clone the code.
git clone https://github.com/Azure-Samples/active-directory-dotnet-native-uwp-v2.git
App.xaml.csfile, set your application/client id copied from the App Registration Portal.
private static string ClientId = "[Application Id pasted from the application registration portal]"
(Optionally): Enable Windows Integrated Authentication when using a federated Azure AD tenant Out of the box, this sample is not configured to work with Windows Integrated Authentication (WIA) when used with a federated Azure Active Directory domain. To work with WIA the application manifest must enable additional capabilities. These are not configured by default for this sample because applications requesting the Enterprise Authentication or Shared User Certificates capabilities require a higher level of verification to be accepted into the Windows Store, and not all developers may wish to perform the higher level of verification. To enable Windows Integrated Authentication, in Package.appxmanifest, in the Capabilities tab, enable:
- Enterprise Authentication
- Private Networks (Client & Server)
- Shared User Certificates Also, in the constructor of the
App.xaml.cs, add the following line of code:
App.PublicClientApp.UseCorporateNetwork = true;
Run the application from Visual Studio (Debug | Start without Debugging), directly on the local machine, or after deploying to a device or an emulator.
Note that if your organization requires Multiple Factor Authentication (MFA), and you try to use the PIN, the certificate will be proposed, but the PIN window won't be presented. This is a known issue with WIA. As a workaround, you might want to use phone authentication (proposed as alternative ways of doing MFA)
Steps to build from scratch
Follow the instructions given in Windows desktop .NET guided walkthrough, but: - Instead of creating a WPF project, you will need to create a UWP project - Instead of using a Label in the
MainWindow.xaml, you will need to use a TextBock (as Labels are not supported in the UWP platform). Intead of the Label Content property, use the TextBlock's Text property - With UWP applications, you don't need to add a cache as it's already managed by MSAL.Net
