I am using Devforce version 6.0.4

Also, when I try to view the entity service (http://iis1/silverlightria/entityservice.svc) I get the following error: "Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service"

 

 

The simplest way to overcome this error is to enable Anonymous Authentication.

You can do that in IIS by selecting your site >> Authentication.

 

If you must run with Anonymous authentication disabled, you should follow the steps below:

- Disable “Anonymous” authentication and enable your authentication of choice for the application’s virtual directory in IIS
- In the web.config, add <location> elements to enable “Anonymous” authentication for all of your .svc files (you still need anonymous authentication to start the service):

      <location path="EntityService.svc">
            <system.webServer>
                  <security>
                        <authentication>
                              <anonymousAuthentication enabled="true" />
                        </authentication>
                  </security>
            </system.webServer>
      </location>
      <location path="EntityServer.svc">
            <system.webServer>
                  <security>
                        <authentication>
                              <anonymousAuthentication enabled="true" />
                        </authentication>
                  </security>
            </system.webServer>
      </location>
    

     
- Unlock the “authentication” elements in the computer’s “applicationHost.config” file.
-- On 32-bit systems: C:\Windows\System32\inetsrv\config
-- Change overrideModeDefault="Deny" to overrideModeDefault="Allow" for all authentication types

                <sectionGroup name="authentication">
                    <section name="anonymousAuthentication" overrideModeDefault="Allow" />
                    <section name="basicAuthentication" overrideModeDefault="Allow" />
                    <section name="clientCertificateMappingAuthentication" overrideModeDefault="Allow" />
                    <section name="digestAuthentication" overrideModeDefault="Allow" />
                    <section name="iisClientCertificateMappingAuthentication" overrideModeDefault="Allow" />
                    <section name="windowsAuthentication" overrideModeDefault="Allow" />
                </sectionGroup>

 

Test by manually browsing to the service file names.

 

I hope this helps,

This is not a DevForce issue, but a Silverlight characteristic.

So disabling anonymous access requires coordinating the settings in IIS and in your service configuration.
