Hi
Joaquim,
Windows Phone 8 apps need to specify the
ID_CAP_MEDIALIB_PHOTO capability to access photos in the media library. After adding it to the WMAppManifest.xml it started working as expected.
As a side note, I have edited your post to remove the link to the project, as it contains dev assemblies, which are not publicly available. In case you need to attach a project, you can open a formal support ticket. This way you will be able to add private attachments.
Best regards,
