In this hands-on lab, we will build an ASP.NET Core Blazor WebAssembly single-page application from scratch. We cover WebAssembly, DOM Updates with the virtual DOM, the differences between Blazor WASM, Server SSR, Server Interactive, and Auto render modes, then move on to app configuration, DI + Options + HTTP Client Factory, layouts, pages and components, lifecycle, routing, binding/validation, forms, and data propagation. We finish with state management, JS interop, and minimal APIs. The labs use a mix of Copilot and development, and if you don't have access to Copilot, the labs fully support that as well.
