Question 1

How does Razor compare to Blazor for web development?

Accepted Answer

Razor is used for server-side rendering in ASP.NET Core MVC, embedding C# in HTML to generate dynamic content on the server. Blazor allows C# to run on the client-side via WebAssembly or server-side with SignalR, enabling full-stack C# development. Razor is better for traditional server-rendered pages, while Blazor suits modern interactive web apps.

Question 2

Can I use Razor with React or other frontend frameworks?

Accepted Answer

Yes, but it's not ideal. Razor can generate HTML that includes React components, but it's primarily designed for server-side views in MVC. For SPAs, consider using Razor Pages for server-side rendering or integrating Blazor for a C#-based frontend, as Razor alone lacks native client-side interactivity.

Question 3

How to set up Razor in a new ASP.NET Core project?

Accepted Answer

When creating a new ASP.NET Core MVC project in Visual Studio or via the .NET CLI, Razor views are included by default. Add .cshtml files and use the @ symbol to embed C# code for dynamic content. Ensure you reference the AspNetCore repo for the latest updates, as the original GitHub project is archived.

Question 4

Is Razor still supported in the latest .NET versions?

Accepted Answer

Yes, Razor is actively developed as part of ASP.NET Core in the main AspNetCore repository. The archived GitHub project is historical; ongoing updates and support are provided through Microsoft's official .NET releases, including .NET 6 and beyond.

Question 5

What are the performance benefits of using Razor over other template engines?

Accepted Answer

Razor is optimized for ASP.NET Core with fast parsing and minimal overhead, leading to efficient HTML generation and reduced server load. However, performance depends on application design, and for highly dynamic content, additional caching or client-side techniques may be needed compared to some JavaScript-based alternatives.

Question 6

How to handle real-time updates with Razor?

Accepted Answer

Razor itself doesn't support real-time updates; you need to integrate JavaScript libraries like SignalR for live data streaming. Razor pages are refreshed on server requests, so for interactivity, combine it with client-side scripting or consider Blazor for a more integrated C# approach.
