Could not get user's information using Microsoft Graph with Application Permissions

Question

I'm using Microsoft Graph SDK with .Net to retrieve a specific user's information such as email address, first name, and last name.

I've created an applications under the Azure B2C and give it the following permissions:

Then, using a console app I've created a new GraphServiceClient and the the following code to retrieve a specific user:

Microsoft.Graph.User graphUser = await MicrosoftGraph.Users[id].Request().GetAsync();

It's returning the right user, but I couldn't retrieve any of the information I needed such as email address.

How can I ask the API the retrieve these info for me and not and empty user?

Answer 1

You can use Select query parameter in your code to return the set of user information

For Example,

var users = await graphClient.Users
    .Request()
    .Select("displayName,Mail")
    .GetAsync();

Answer 2

You cannot use MS graph api for Azure B2C. B2C currently cannot call MS Graph API. You must use Azure AD Graph API to manage users in Azure AD B2C directory.

please see:here and here.

Answer 3

I did find an answer for that here.

It seems that the full functionalities for B2C are only available using Microsoft Graph Beta.
