How to Serve Static Files in ASP.NET Core?

Static files in ASP.NET Core include CSS, JavaScript, images, fonts, and HTML files that are served directly to clients without server-side processing. ASP.NET Core provides middleware to serve static files efficiently and securely.

Key Features:

• Supports serving files from wwwroot folder
• Middleware handles static file requests
• Enables caching for performance
• Can serve files from multiple directories
• Works with MVC, Razor Pages, and APIs

Example:
Enable static files in Program.cs:

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

app.UseStaticFiles(); // Serve files from wwwroot

app.MapGet("/", () => "Hello Static Files!");

app.Run();

Folder structure:

wwwroot/
   css/
   js/
   images/

Serving static files in ASP.NET Core allows faster content delivery and improves user experience by offloading simple requests from server-side processing.
