ASP.NET MVC - Catch All Route And Default Route

Question

In trying to get my application to produce 404 errors correctly, I have implemented a catch all route at the end of my route table, as shown below:

 routes.M

Ah, the problem is your default route catches all 3 segment URLs. The issue here is that Routing runs way before we determine who is going to handle the request. Thus any three segment URL will match the default route, even if it ends up later that there's no controller to handle it.

One thing you can do is on your controller override the HandleMissingAction method. You should also use the tag to catch all 404 issues.
