It looks like there's a missing permission scope that the people picker needs: People.Read. If you add that scope to your OAuth.resw does it help?

I would also recommend investigating replacing the Microsoft.Toolkit.Graph.Controls (which is deprecated) with their recommendation: CommunityToolkit.Graph.Uwp. I'm planning to update this sample to use it when I can.

Hello @jasonjoh,
Thank you for replying.

I added your suggested permission and people picker is working fine now. But I am getting inconsistence sign in behavior in the application. It is asking me for sign in again even though I already signed in into the application[See attached screenshot].

I also tried with "CommunityToolkit.Graph.Uwp" nuget packages. But I am getting singout state after sign in. Please check this issue. CommunityToolkit.Graph.Uwp issue

Closing as we've updated to use the CommunityToolkit.Graph.Uwp packages, and I cannot reproduce the second issue mentioned.
