WebAPI Error 404.0 - Not Found

Question

We are having problems deploying our WebAPI service on our production server. When we try to access the controller, we get "The resource you are looking for has been deleted, its name has changed or is temporarily unavailable."

We created a new project from the standard WebAPI template and it has the same problem, so this is definitely not our code that causes the problem. We also have another server with the same hosting company, and when deployed to this, everything works fine. All IIS features are identical between servers.

At one stage, we had an application pool installed in the .Net Framework 2.0, and the site did not complain about it, so it did not even try to deploy the service. We also have the odata service in the same web application, and everything is working fine. Therefore, it seems to be related to MVC and WebAPI routing.

We copied all the DLLs that we could come up with on the server, but nothing fixed the situation.

Does anyone have any ideas on what might be different between the two servers that might cause the error above?

Thank you in advance

try this article

HTTP Error 404.0 0 Not Found in MVC

or

or try adding the following to Web.config:

<system.webServer> <modules runAllManagedModulesForAllRequests="true"/> </system.webServer>

This error message also appears when starting your WebApi using OWIN, and you forget to include the following line in your startup class:

 app.UseWebApi(config);
