What new topics or skills have you recently studied for your professional growth?

Recently, I studied the new features of C# 10 and 11, such as global using directives, improved pattern matching, and enhancements in working with nullable types. I also learned how to work with the System.Text.Json library for more efficient serialization and deserialization of data.

Example of using global using:

// In the GlobalUsings.cs file
global using System;
global using System.Collections.Generic;

// Now, these namespaces do not need to be explicitly specified in other files

This helps reduce the amount of repetitive using directives in each file and makes the code cleaner.
