Razor Masterclass: Building Dynamic UIs
Razor is not just "HTML with C#". It is a powerful, compiled view engine that supports modularity, reusability, and clean UI code.
Layouts, _ViewStart, and _ViewImports
These 3 files are the foundation of your UI structure. _ViewStart tells Razor which layout to use by default, while _ViewImports provides common namespaces and Tag Helpers to all your views.
Expert Pattern: Razor Sections
Sections allow you to define content in your view that is then rendered in a specific placeholder in your layout. This is perfect for page-specific scripts or meta tags.
// In Layout
<head>@RenderSection("MetaTags", required: false)</head>
// In View
@section MetaTags { <meta name="description" content="Product Page"> }
