Getting Error reading JObject from JsonReader. Current JsonReader item is not an object: String. Path 'userPurpose' in the Demo project.

[spartan1047]

Where did you get the code?

• [X ] Downloaded from GitHub
• Downloaded from the Microsoft Graph quick start tool
• [ X] Followed the tutorial from Microsoft Graph tutorials

Describe the bug
Is not possible to get the MailboxSettings with the projects as it is. If you run the project you get a Newtonsoft.Json.JsonReaderException, this happen following the tutorial o downloading the demo project from github, in both cases I have replaced the AppID with my own id.
To Reproduce
Steps to reproduce the behavior (for the demo):

1. Open the solution
2. Rename the OAuth.resw.example to OAuth.resw
3. Added my AppID
4. Run the app
5. Login with my account
6. The app displays my name over the top-right corrner.
7. Press Calendar.
8. The exception is displayed.

Expected behavior
I'm expecting to see the calendar as the tutorial and documentation indicates.

@spartan1047 sorry you're having trouble! This seems to be an issue with the very old version of the Graph SDK that the (deprecated) Microsoft.Toolkit.Graph.Controls package. The userPurpose field was added to mailboxSettings after that version was released.

I suspect the answer here will be to replace Microsoft.Toolkit.Graph.Controls with CommunityToolkit.Graph.Uwp. I'm not sure how much effort that entails at this point, but I'll take a look ASAP.

@jasonjoh Hello, thanks for the commit, I have downloaded the changes but still not working, in Windows 10, after I type my password nothing happens. In Windows 11, I'm getting an error:

[jasonjoh]

Oh yes, sorry! This is an issue with the new toolkit (see CommunityToolkit/Graph-Controls#188). For now add the redirect URI the error is showing you to your app registration (under Authentication).

Better solution:

// Configure MSAL provider
var msalClient = PublicClientApplicationBuilder.Create(appId)
    .WithRedirectUri("https://login.microsoftonline.com/common/oauth2/nativeclient")
    .Build();
ProviderManager.Instance.GlobalProvider = new MsalProvider(msalClient, scopes.Split(' '));

Commit incoming.

Thank you for the help, I have downloaded the latest version of the project, but the behavior is a little bit weird. When I run the app for first time (or when I'm not logged in) after I type my password the app freezes and displayes this dialog:

If I close it, I return tot he UWP logged in.

I don't reproduce it with either a personal account or a work/school account. I do see these GitHub issues:
