No type was found that matches the controller named 'User'

Question

I\'m trying to navigate to a page which its URL is in the following format: localhost:xxxxx/User/{id}/VerifyEmail?secretKey=xxxxxxxxxxxxxxx

I\'ve added a new route i

Answer 1

In my case, the routing was defined as:

 config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "{*catchall}",
            defaults: new { controller = "WarehouseController" }

while Controller needs to be dropped in the config:

 config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "{*catchall}",
            defaults: new { controller = "Warehouse" }

Answer 2

In my case it was a case of over-aggressive caching by the WebHostHttpControllerTypeResolver.

Fix:

1. Delete all files (or in my case just any files named "MS-ApiControllerTypeCache.xml") under this path:

   C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root

2. Restart the app pool

Answer 3

In my case, the controller was defined as:

    public class DocumentAPI : ApiController
    {
    }

Changing it to the following worked!

    public class DocumentAPIController : ApiController
    {
    }

The class name has to end with Controller!

Edit: As @Corey Alix has suggested, please make sure that the controller has a public access modifier; non-public controllers are ignored by the route handler!

Answer 4

In my case I wanted to create a Web API controller, but, because of inattention, my controller was inherited from Controller instead of ApiController.

Answer 5

Another solution could be to set the controllers class permission to public.

set this:

class DocumentAPIController : ApiController
{
}

to:

public class DocumentAPIController : ApiController
{
}

Answer 6

In my case I was seeing this because I had two controllers with the same name:

One for handling Customer orders called CustomersController and the other for getting events also called CustomersController

I had missed the duplication, I renamed the events one to CustomerEventsController and it worked perfectly
