 ## Coding Standards
 
 ### C# Guidelines
-- Use C# 13 features and modern .NET patterns
+- Use C# 14 features and modern .NET patterns
 - Prefer primary constructors for dependency injection
 - Use `var` for obvious types, explicit types for clarity
 - Implement proper async/await patterns for I/O operations
 - Use nullable reference types consistently
 - Prefer "target-typed new"
 - Prefer "list initializer" over new
+- Package versions are managed centrally in Directory.Packages.props
 
 ### Avalonia-Specific
 - Follow MVVM pattern strictly
+- x:Name does work for making components accessible in code-behind
 - ViewModels should inherit from appropriate base classes
 - Use ReactiveUI patterns where applicable
 - Make use of annotations to generate bindable properties
