Key Features
Tuned for fast WebAssembly download and AOT delivery
- Client-Side Execution — Run C# code directly in the browser via WebAssembly with full browser API access
- HTTP/3 + Brotli Compression — WASM bundles served over HTTP/3 with multiplexed streams; Brotli reduces transfer size by ~70% vs gzip
- AOT-Friendly Handlers — IIS handlers respect Native AOT cache headers, application/wasm MIME, and integrity attributes Blazor expects
- SPA Fallback Routing — URL rewriting configured for client-side routing so refresh and deep-links resolve to index.html
- Offline / PWA — Service worker registration supported for Progressive Web App scenarios with offline-first behaviour
- Pre-rendering Support — ASP.NET 8 LTS+ server-side prerendering for first-paint SEO and faster perceived load
