PubCenter ads are not displaying with adrotator

Question

I'm using AdRotator in my WP8 app, and while AdDuplex ads display just fine, PubCenter ads are not displaying. I saw that it was normal it does not appear in emulator. But I tested "device" mode and it does not appear either. I also tried to publish my app with 50/50 parameter for AdDuplex and PubCenter, and the only advertisements we see are those of AdDuplex.

Note that I use AdDuplex version 2.1.0-Beta1.

Here's my xaml:

<adRotator:AdRotatorControl 
                    x:Name="AdRotatorControl"
                    Grid.Row="3"
                    AdHeight="80" AdWidth="480"
                    Margin="-12,253,0,-243"
                    LocalSettingsLocation="defaultAdSettings.xml"
                    AutoStartAds="True" />

And the 'defaultAdSettings.xml' file :

<?xml version="1.0" encoding="utf-8"?>
<AdSettings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <CultureDescriptors CultureName="">
    <AdDuplex AppId="950XX" Probability="50"/>
    <PubCenter AppId="767b12XX-bcXX-41XX-a5XX-333ba4afb0XX" SecondaryId="107299XX" Probability="50"/>
    </CultureDescriptors>
</AdSettings>

Even if I specify the parameters 100 (pubCenter) / 0 (AdDuplex) nothing appears. And i have checked thoses capabilities :

<Capability Name="ID_CAP_IDENTITY_USER"/>
<Capability Name="ID_CAP_MEDIALIB_PHOTO"/>
<Capability Name="ID_CAP_NETWORKING" />
<Capability Name="ID_CAP_PHONEDIALER" />
<Capability Name="ID_CAP_WEBBROWSERCOMPONENT" />

Someone would have an idea why my PubCenter ads do not appear?

Answer 1

I found the solution by myself after long searches. To use "pubCenter" with "AdRotator", the following points should be well done:

1) Having checked the Capacities

<Capability Name="ID_CAP_IDENTITY_USER"/> 
<Capability Name="ID_CAP_MEDIALIB_PHOTO"/> 
<Capability Name="ID_CAP_NETWORKING" /> 
<Capability Name="ID_CAP_PHONEDIALER" /> 
<Capability Name="ID_CAP_WEBBROWSERCOMPONENT" /> 

2) Add reference to the Microsoft Advertising SDK

My mistake here was to have forgotten the reference to the SDK. But now everything works fine :)
