Thank you! This PR updates the Blazor Maui Web template to use the modern ASP.NET Core `MapStaticAssets()` middleware instead of the legacy `UseStaticFiles()` middleware. ## Changes Made In `src/Templates/src/templates/maui-blazor-solution/MauiApp.1.Web/Program.cs`: - **Removed:** `app.UseStaticFiles();` call - **Added:** `app.MapStaticAssets();` call placed before `MapRazorComponents()` ```diff app.UseHttpsRedirection(); - app.UseStaticFiles(); app.UseAntiforgery(); + app.MapStaticAssets(); + #if (UseServer && UseWebAssembly) app.MapRazorComponents<App>() ``` ## Benefits `MapStaticAssets()` is the recommended approach for serving static assets in modern ASP.NET Core applications as it: - Provides better performance through optimized asset serving - Enables improved caching strategies - Offers better integration with the routing pipeline - Follows current ASP.NET Core best practices ## Testing - ✅ Template generation works correctly with `dotnet new maui-blazor-web` - ✅ Generated web projects build successfully - ✅ Static assets (CSS, JS) are served correctly at runtime - ✅ All HTTP requests to static files return expected responses Fixes #31617. ## Progress - [x] Implement the core change from UseStaticFiles() to MapStaticAssets() - [x] Revert unrelated changes to cgmanifest.json and templatestrings.json files - [x] Verify the template still works correctly  --- 💬 Share your feedback on Copilot coding agent for the chance to win a $200 gift card!
