Summary

Microsoft's Blazor framework eliminates the frontend-backend language divide by allowing developers to write interactive UIs using only C# and HTML. By running code on WebAssembly or server-side via SignalR, it introduces a unified ecosystem where logic, models, and validations are seamlessly shared across the entire stack.

Key Topics

• Blazor WebAssembly: A hosting model where C# code is compiled into WebAssembly and executed directly in the browser. It enables high-performance, offline-capable applications that run at near-native speeds.
• Blazor Server: A model where the application logic runs on the server and UI updates are pushed to the client via a persistent SignalR connection. This minimizes the initial download size and keeps sensitive logic safely on the server.
• Code Sharing: The ability to use the same C# classes, DTOs, and validation logic in both frontend and backend code. This reduces redundancy and ensures that business logic remains synchronized across the entire stack.
• SignalR: An open-source library that simplifies adding real-time web functionality to apps. In Blazor Server, it acts as the communication tunnel that synchronizes the UI state between the browser and the server.

Key Takeaways

• Initialize a Blazor project using the ASP.NET Core template to compare Server and WebAssembly hosting models.
