Blazor in .NET 8: Mastering the New Render Modes and Building Interactive Web Apps
summary
Shows concrete .NET 8 results: demos use the web app and webassembly templates, combine Auto render mode (pre-render → SignalR → background WASM download), demonstrate streaming server-side rendering that sends partial HTML while data loads, and implement persistent component state (JSON baked into the page) to avoid double fetches. Builds working weather and delayed-stream demos plus a Visual Studio “Blossom” extension; most demos run but reveal preview hiccups. Claims production use since 2019 and practical startup-performance fixes.
