Introducing Razor Components in ASP.NET Core 3.0
summary
ASP.NET Core 3.0 ships Razor Components (same component model used in Blazor) so UI logic runs in C# and either executes server-side over SignalR (thin client, ~100KB initial download, UI diffs sent as small frames) or client-side via WebAssembly (DLLs and runtime ≈2 MB after linking). Demos show counters, reusable parameterized components, two‑way binding, a to‑do app, ML.NET sentiment analysis kept on the server, Azure SignalR for large-scale connections, and an Electron-hosted desktop experiment — all working end-to-end in the preview.
