One line to handle null in C#

Summary

The transcript discusses a new feature in C# 10 for handling null argument checks, specifically the `ArgumentNullException.ThrowIfNull()` method. This approach simplifies null validation by reducing boilerplate code and automatically using the input argument's name when throwing an exception. The practical takeaway is that developers can now write cleaner, more concise code for method guards and constructors by using this single-line null checking mechanism.
