.NET 6 RC1: Reviewing the Final Features

Release Candidate 1 is out. This means the API surface is stable. It’s “Go Live” supported for production.

DateOnly and TimeOnly

Finally! We no longer need to use `DateTime` with “00:00:00” time for birthdays. These new structs align with SQL `date` and `time` types perfectly.

DateOnly birthday = new DateOnly(1999, 1, 1);
TimeOnly alarm = new TimeOnly(7, 0);

PriorityQueue

A new collection type `PriorityQueue<TElement, TPriority>` has been added. Essential for pathfinding algorithms (A*) or job scheduling systems.

var queue = new PriorityQueue<string, int>();
queue.Enqueue("Clean dishes", 2);
queue.Enqueue("Feed cat", 1); // Higher priority (lower number)

var next = queue.Dequeue(); // "Feed cat"
