Changes

• Add common data types to “Variables and Data Types” section
  • DateTime
  • Guid
• Add new “Nullability” section, including:
  • Nullable value types
  • Nullable reference types
  • Null coalescing operator
  • Null-conditional assignment
• MoveException Handling up, since it’s important for most codebases.
• Change text on “Extension methods” to “Extension members”, since C# 14 introduces the ability to extend both methods and properties
• Move enums from “Going Deeper” section to “Learn the Fundamentals” section, since enums are much simpler and more commonly used than the other advanced features
• Move static into “Member Modifiers” section
• Center-align last item in group to center if the group has an odd count

Notes for C# 14

The most impactful feature of C# 14 (imo) that may impact most codebases is the new Null-conditional assignment feature. This has been added to the new Nullability section.
