" summary

Explains that binary formatter moves to a NuGet fallback in .NET 9 and shows a real resx leak where a “special property” with customer data was serialized, then demonstrates net 9 analyzers flagging unconfigured serializable properties (defaults to build-break but configurable; thousands of hits expected on upgrade). Shows experimental dark mode + visual styles (rounded controls, toggles, title bar color) and new invoke async / form show async APIs that keep the UI responsive during concurrent drawing. Ends with a working Semantic Kernel demo parsing human dates into concrete due dates for a to‑do app.
