Razor Pages for Front-End Devs: Modern Workflows in Visual Studio
Modernizing the Razor Workflow
Coming from a world of Vite and Svelte, Visual Studio can feel heavy. But for a UI-first developer, Razor Pages is actually a 'Super-HTML' environment. By layering modern front-end tools like Gulp and SCSS over the robust .NET 8 framework, you get the best of both worlds.
1. The Pro UI Editor Setup
First, we make Visual Studio 2022 behave like a modern code editor. Consistency in indentation and formatting is the foundation of a clean codebase.
- Formatting: Use
Ctrl + K, Ctrl + Dto format the entire document instantly. - Auto-Format: Enable 'Format on Save' under
Tools → Options → Text Editor → HTML → Advanced. - Extension: Install Web Essentials 2022 for better syntax highlighting and alignment within
.cshtmlfiles.
2. Integrating SCSS & Live Reload
Don't settle for standard CSS. We can use Gulp to proxy our .NET server, giving us SCSS compilation and BrowserSync auto-refresh.
// gulpfile.js snippet
function serve() {
browserSync.init({
proxy: "https://localhost:7048", // Matches your VS IIS Express URL
notify: false
});
gulp.watch("wwwroot/scss/**/*.scss", styles);
gulp.watch("Pages/**/*.cshtml").on('change', browserSync.reload);
}The Directory Secret: For the best experience, move your package.json and node_modules to the project root, keeping your source assets in wwwroot/scss.

3. Razor Fundamentals
Understanding the core directives is key to moving data from C# to the screen.
- @page: This makes the file a reachable URL. Without it, the file is just a snippet.
- @model: Connects your UI to a C#
PageModel. This is your 'code-behind' where logic lives. - @RenderBody(): Found in
_Layout.cshtml, this is the slot where your specific page content is injected.
6. The UI Architecture Trinity
As a front-end developer, you need to know which 'component' type to reach for. Here is the breakdown of Partials, View Components, and Tag Helpers.
A. Partials (The 'Snippets')
When to use: For static or simple UI chunks that rely on the parent page's data (e.g., a site footer or a simple contact form).
<div class="card">
<h3>@Model.Name</h3>
</div>
<partial name="_UserCard" model="Model.CurrentUser" />B. View Components (The 'Widgets')
When to use: When a UI piece needs its own data logic independent of the page it sits on (e.g., a dynamic Sidebar that pulls from a database, or a complex Shopping Cart summary). Usually we are 'returning' something at his point.
// The 'Code-Behind' for a View Component
public class PriorityListViewComponent : ViewComponent {
public async Task<IViewComponentResult> InvokeAsync(int maxItems) {
var items = await _service.GetItemsAsync(maxItems);
return View(items);
}
}C. Tag Helpers (The 'Attributes')
When to use: To extend existing HTML elements with server-side logic (e.g., adding validation to an input or conditionally hiding a button).
<button asp-if="@Model.IsAdmin" class="btn-delete">Delete Post</button>Decision Matrix
| Feature | Partial | View Component | Tag Helper |
|---|---|---|---|
| Own Logic? | No | Yes (Independent) | No (Attribute based) |
| Complexity | Low | High | Medium |
| Best For | DRY HTML | Mini-Apps/Widgets | HTML Augmentation |
<form method="post">
<label>User Email</label>
<input type="email" asp-for="UserEmail" />
<button type="submit">Register</button>
</form>Cheat Sheet: Visual Studio & Razor Shortcuts
| Action | Shortcut |
|---|---|
| Format Document | Ctrl + K, Ctrl + D |
| Format Selection | Ctrl + K, Ctrl + F |
| Run Project (Debug) | F5 |
| Open Terminal | Ctrl + ` |
| Build Solution | Ctrl + Shift + B |
*Pro Tip: Always run 'npx gulp' AFTER launching your project with F5 to ensure the proxy connects correctly!*
