Serving favicon.ico in ASP.NET MVC

How to Serve Favicon.ico in ASP.NET MVC 🖼️

You're building a cool ASP.NET MVC application, and now it's time to spice it up with a customized favicon.ico! But wait, you're facing some issues and have a couple of questions. Don't worry, we've got you covered! In this blog post, we'll address common problems and provide easy solutions to serve favicon.ico in your ASP.NET MVC application. So, let's dive in! 💦

The Common Approach 🛣️

Before we get into the specifics, let's take a quick look at the common approach many developers use:

1. Ignoring the route: You start by adding an entry to your RegisterRoutes method to ignore the favicon.ico route:

   routes.IgnoreRoute("favicon.ico");

2. Placing favicon.ico: Next, you place the favicon.ico file in the root directory of your application, which happens to be the root of your domain as well.

The Burning Questions 🔥

Now, let's address the burning questions you have:

1️⃣ Can I place favicon.ico somewhere other than the root directory? 📂

Unfortunately, ASP.NET MVC expects the favicon.ico file to be in the root directory. It might feel a bit awkward, especially when you have other important files, like Content and Controllers, at the same level. But fear not! We have a solution that might ease your concerns. 😉

You can create a subdirectory, let's say StaticFiles, and move your favicon.ico file there. Then, modify your route ignoring entry like this:

routes.IgnoreRoute("StaticFiles/favicon.ico");

With this approach, you can keep your root directory cleaner and enjoy a neatly organized application structure.

2️⃣ Is the IgnoreRoute statement sufficient, or should I do more? 🚦

While the IgnoreRoute("favicon.ico") statement is usually sufficient for most cases, it's great to be aware of additional options, just in case.

The blog post by Phil Haack mentioned by you here dives deep into the topic of ignoring requests with specific file extensions.

To follow this approach, you can use the following IgnoredRoute entry:

routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });

This route ignores requests for favicon.ico in any directory other than the root. It offers more flexibility, but for most scenarios, the simpler IgnoreRoute("favicon.ico") should suffice.

Your Turn! 💪

Now that you have a better understanding of serving favicon.ico in your ASP.NET MVC application, it's time to take action! Here's your call-to-action:
