Repro

IPublicClientApplication app = PublicClientApplicationBuilder.Create(ClientId).WithAuthority($"https://login.microsoftonline.com/{Tenant}/v2.0").Build();

Expected behavior The call method returns an IPublicClientApplication that I can use to obtain the token

Actual behavior The system launch this exceptions: ERROR: Exception during construction of EventSource Microsoft.Identity.Client: Unable to load DLL ‘advapi32.dll’: The specified module could not be found.

ERROR: Exception during construction of EventSource System.Collections.Concurrent.ConcurrentCollectionsEventSource: Unable to load DLL ‘advapi32.dll’: The specified module could not be found.

Additional context/ Logs / Screenshots The same method works good in if I build it in mono backend in Android The same method works good if I build it for UWP solutions

If you say that the latest newtonsoft works with unity, then we can update our internal copy to latest as well.

Unfortunately Newtonsoft doesn’t want to make his libraries compatible with Unity. But there is a fork of Newtonsoft that works with unity and it’s updated to the latest version of newtonsoft (12.0). probably you will take only the fix that the fork do to solve the problem. https://github.com/jilleJr/Newtonsoft.Json-for-Unity

Here the core of the fork: This repo is a fork of JamesNK/Newtonsoft.Json containing custom builds for regular standalone, but more importantly AOT (Ahead Of Time) targets such as all IL2CPP builds (WebGL, iOS, Android, Windows, Mac OS X) and portable .NET (UWP, WP8).
