404 errors for PUT and DELETE requests on deployed WCF RESTful Service

Question

I have deployed an MVC3 and WCF web service as a single application. Both work as expected. GET and POST requests work perfectly, but the PUT and DELETE requests return 404 errors. These work fine locally. Initially it was requesting a username/password for PUT/DELETE requests.

Here is my WebServer config from my web.config file

    <system.webServer>
        <validation validateIntegratedModeConfiguration="false" />
        <modules runAllManagedModulesForAllRequests="true">
            <remove name="WebDAVModule" />
        </modules>
        <handlers>
            <remove name="WebDAVModule" />
        </handlers>     
        <security>
          <authorization>
            <remove users="*" roles="" verbs="" />
            <add accessType="Allow" users="*" 
                            verbs="GET,HEAD,POST,DEBUG,PUT,DELETE" />
          </authorization>
        </security>             
    </system.webServer>

Here are my PUT and DELETE methods:

    [OperationContract]
    [WebInvoke(UriTemplate = "{id}", Method = "PUT")]
    public MyResource Put(MyResource updatedResource, int id)
    {
        MyResource existingResource = Database.GetResourceById(id);
        existingResource.Name = updatedResource.Name;
        Database.SaveResource(existingResource);

        return existingResource;
    }

    [OperationContract]
    [WebInvoke(UriTemplate = "{id}", Method = "DELETE")]
    public MyResource Delete(int id)
    {
        MyResource sampleResource = Database.DeleteResourceById(id);
        return sampleResource;
    }

My set up:

• .NET 4.0
• MVC3
• IIS 7.0

Note: I am on a shared hosting plan, therefore do not have direct access to IIS7.0 a so I need to make changes via the web.config file.

Enable Tracing on your service and see why you get a 404 error when you try for a PUT or DELETE action.
