Asp.NET Web API - 405 - HTTP verb used to access this page is not allowed - how to set handler mappings

Question

I wrote REST service using ASP.NET Web API. I'm trying to send HttpDelete request, however I get the following error:

405 - HTTP verb used to access this page is not allowed

I think I'm close to the solution, I found out that I should enable IIS remote management , go to Handler Mappings section and add DELETE verb to the appropriate position... but the problem is that there is a lots of different positions on the list... (sth like here: http://www.somacon.com/p126.php).

Which one should I edit? Few of them don't have extension, e.g. "ExtensionUrlHandler-Integrated-4.0" and I added DELETE verb to it, but it still doesn't work...

It was just a shot in the dark to modify that one, so should I modify different position? If so, which one? Or maybe is there anything more what I should do?

The same web service work perfectly fine on my local service, so I guess the problem is with the remote IIS...

Greetings

You don't need to uninstall WebDAV, just add these lines to the web.config:

<system.webServer>
  <modules>
    <remove name="WebDAVModule" />
  </modules>
  <handlers>
    <remove name="WebDAV" />
  </handlers>
</system.webServer>
