Why does HTTP DELETE verb return 405 error – method not allowed for my RESTful WCF service running on IIS 7.5?

In case anyone having the same issue.

Here is another way you can try.

in web.config

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