Many developers are still using .NET Core 3.1, even though it reached EOL in 2022.

We have now reached .NET 9, and each previous version came with some improvements and new functionalities.

In this session, we will explore the most important things a .NET developer should know about the newest versions of the framework.

We will cover different topics, such as:

- new syntax (eg: new() for object initialization, primary constructor for classes, and more)
- new data types (eg: record types, PriorityQueues, DateOnly)
- new methods (eg: LINQ's minBy, ArgumentException's guard clauses)

This session targets C# developers who are aware that new versions of .NET are available but have missed the improvements in the latest releases.

On average, this session takes 1 hour. I can add or remove topics to adjust its duration.
