# WebAssembly
The Blazor AI Migrator is expanding to support Blazor WebAssembly (WASM), offering a powerful alternative to the server-centric LiveView model. This addition allows your migrated applications to run C# code directly in the user's browser, bringing the web experience even closer to the performance of the original desktop app.
#### ⚡ What is Blazor WebAssembly?
WebAssembly is a modern web standard that enables high-performance, binary code to run in the browser. In this model, the .NET runtime and your application assemblies are downloaded to the client machine, allowing the app to execute locally without a constant "tether" to the server.
Blazor Server vs Blazor WebAssembly
#### 🌟 Key Benefits of the WASM Model
By adding WebAssembly support, the migrator offers new strategic advantages for your modernized apps:
* Offline Capability: Unlike the server model, WASM apps can continue to function even if the internet connection is interrupted, as the logic lives in the browser.
* Zero Latency Interactivity: UI events (like clicking a tab or opening a menu) happen instantly on the client, eliminating the "network hop" required by the LiveView/SignalR model.
* Server Offloading: Processing power is shifted from your expensive cloud servers to the user's own hardware, significantly reducing hosting costs for high-traffic applications.
* Static Hosting: WASM apps can be served from simple, cost-effective storage like a Content Delivery Network (CDN) or Azure Static Web Apps, as they don't require a full ASP.NET Core server to run.
Main difference
#### 🛠️ Updated Installation for WASM Support
To enable these features, you must add the following to your environment:
1. WASM Build Tools: In the Visual Studio Installer, select the .NET WebAssembly build tools option under the ASP.NET and web development workload.
2. CLI Command: Alternatively, you can run `dotnet workload install wasm-tools` from an administrative prompt.
3. Project Configuration: Your project will now include a `` property to trigger high-performance native execution.
