Blazor is Microsoft's framework for building browser-based UIs using C# instead of JavaScript. WebAssembly deployment runs C# directly in browsers, enabling .NET developers to skip JavaScript entirely. Strong for line-of-business apps, less common for consumer products.

What is Blazor WebAssembly

Blazor is Microsoft's framework for building interactive web applications using C# and .NET. Blazor WebAssembly compiles C# to WebAssembly (WASM), running directly in browsers without server round-trips. It enables .NET developers to build full-stack applications without learning JavaScript. Component-based architecture mirrors React/Vue, familiar to web developers. - C# in Browser: .NET developers can skip JavaScript; reuse backend knowledge for frontend

❓ FAQ

▶Should I use Blazor Server or Blazor WebAssembly?
Server for LOB apps (lower payload, real-time sync). WebAssembly for offline, PWA, light clients.
▶How large is a Blazor WebAssembly app download?
~2-3MB initial (runtime + framework). Gzipped ~1MB. Larger than JavaScript frameworks but acceptable.
▶Can I use Blazor for real-time applications like gaming?
Possible but not ideal; latency from WebAssembly execution is higher than optimized JavaScript. Use JavaScript for games.
▶How do I optimize Blazor WebAssembly performance?
Enable AOT compilation, tree-shake unused code, lazy-load assemblies, optimize component rendering with @key directive.
▶Can I call JavaScript from Blazor C# code?
Yes, via JS Interop; call C# from JavaScript too. Useful for third-party libraries not available in .NET.
▶What is the ecosystem for Blazor components?
Syncfusion, MudBlazor, Radzen offer component libraries. Smaller ecosystem than React but growing.
▶Can I deploy Blazor to production without ASP.NET Core backend?
Yes, static Blazor apps deploy to CDN (GitHub Pages, Azure Static Web Apps). Optional backend for data.
