asp.net - mvc: does the favicon.ico also look for a controller?

Question

I get an error:

"The controller for path '/favicon.ico' was not found or does not implement IController"

Then I thought: how does the framework know for which files it has to instantiate a controller, because the same thing is true for script, css and other files?

(never thought of that, but now the favicon is complaining, I was wondering....)

But back to the error, why does that occur?

Answer 1

Add this to you global.asax:

routes.IgnoreRoute("favicon.ico");
