Confusion with nullability of a custom LINQ method
I have this custom extension method I used a lot in my project, however every time I use it, it trips nullability checks and thinks I'm using a possibly null value. ```csharp

/// Tries to get the first item that meets a condition from a collection. /// </summary> /// <typeparam name="T">Type of items in the collection</typeparam>...

The second time, when the JWT expires and a refresh token is sent, the cookie still doesn’t appear...

[Microsoft.StylusInput] Deployed software is suddenly not working anymore after a Windows update
After 8 years without any issues, we just got many reports that an exception is now triggered, related to .NET's Code Access Security. Is there a way to avoid this without resuscitating and modifying this old project? And how to know what recent change triggered this issue?

Difficulty Retrieving MeetingId for Teams Meeting Created via Calendar Event using Microsoft Graph.
I am working on integrating Microsoft Teams meetings with a .NET 6 backend using the Microsoft Graph API. In my implementation, I create calendar events with online meetings enabled by setting IsOnlineMeeting = true on the event object. The creation of the meeting itself works fine, and I receive a joinUrl link which attendees can use to join the meeting.
However, I face a significant challenge: I need to programmatically retrieve the Teams meeting ID (meetingId) after creating the event, which is crucial for functions like fetching attendance reports and meeting insights....
