When a static server-rendered Blazor page becomes interactive, its components start over, re-fetching data the server already rendered, flashing loading indicators over finished content, and tempting developers toward global state containers that leak between users.
When a static server-rendered Blazor page becomes interactive, its components start over, re-fetching data the server already rendered, flashing loading indicators over finished content, and tempting developers toward global state containers that leak between users. In this course, Data Hydration and State Persistence in ASP.NET Core 10 Blazor, you'll gain the ability to carry state cleanly across the SSR-to-interactive boundary. First, you'll explore how the hydration handoff works and see the double-fetch and flicker problem live. Next, you'll discover how the[PersistentState] attribute serializes server-fetched data into the page and restores it during interactivity, including what's really in the persisted payload, and what must never go in it. Finally, you'll learn how to share per-user state safely with scoped services, cascading values, and persistent service registration, and how to architect your data flow so every piece of state has exactly one home. When you're finished with this course, you'll have the skills and knowledge of data hydration and state persistence needed to build SSR-first Blazor applications that become interactive without re-fetching, flickering, or leaking state.
