How do I enable HTTP PUT and DELETE for ASP.NET MVC

Share |

1. GO to Handler Mappings in your IIS Manager. 
2. Find ExtensionlessUrlHandler-Integrated-4.0, 
3. double click it. 
4. Click Request Restrictions... button and on Verbs tab, add both DELETE and PUT. 

Remove WebDav from "Modules" and from "Handler Mappings"

Modules:

                WebDAVModule, %windir%\System32\inetsrv\webdav.dll, Native, Inherited

Handler Mappings:

                WebDAV, *, Enabled, Unspecified, WebDAVModule, Inherited

Then Restart IIS

It results in a Web.Config change of:

  <system.webServer>

        <modules>

            <remove name="WebDAVModule" />

        </modules>

        <handlers>

            <remove name="WebDAV" />

        </handlers>

  </system.webServer>
