Hello Kurt Landuyt,
Currently, the WrapAround mode for Silverlight is not included in our roadmap for the upcoming releases. We logged this feature request in our Feedback Portal
where you can vote for its implementation. By voting, you are increasing its priority. In case this request is of interest to more people and gathers enough votes so its priority gets high enough, then we will consider it and make it part of our future plans.
