What are View Components in ASP.NET Core? See Example

View Components in ASP.NET Core are reusable components that render HTML content in Razor views. They are similar to partial views but encapsulate logic and data fetching, allowing developers to reuse UI across multiple pages.

Key Features:

• Encapsulate rendering logic and data
• Reusable across multiple views
• Supports asynchronous operations
• Integrates with dependency injection
• Enhances maintainability and modularity

Example:
Creating a simple View Component:

public class PopularProductsViewComponent : ViewComponent
{
    public IViewComponentResult Invoke()
    {
        var products = new List<string> { "Laptop", "Mobile", "Tablet" };
        return View(products);
    }
}

Razor view usage:

@await Component.InvokeAsync("PopularProducts")

View Components in ASP.NET Core are ideal for modular UI development, allowing developers to reuse components with embedded logic efficiently.
