Why is a Required * path parameter {namespace} getting detected by Swagger?

Question

My .Net MVC project has the below ApiController:

But the Swagger UI generates two methods:

Observe that the ActionName TestMethod1 is omitted(probably because there is only one HttpGet in this controller)

There must be something else, the code you show here should not cause that issue, create a new project that can reproduce this and paste a link I would be happy to look into it — Helder Sepulveda, Dec 19 '20 at 17:04

This was due to the DefaultRoute not having the {action} in the path.

 routes.MapRoute(
                name: "Default",
                url: "{controller}/{id}",
                defaults: new { controller = "Addon", action = "Index", id = UrlParameter.Optional }
            );

It should be like:

 routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Addon", action = "Index", id = UrlParameter.Optional }
            );
