The present thread contains no official response from Telerik. Basically, forum posts are meant as a place for the community to exchange ideas/solutions, rather than a guaranteed way to get support, although we always review all forum threads. Additionally, I will ask you to refrain from using such strong language, as it really does not help neither you, nor the community, and is rather detrimental to resolving the issue.
To address any problem that you are having, you can consider opening a formal support ticket, and providing the relevant details, or doing so in this forum thread. Based on this information, we will provide more information on how to work around/resolve the problem. Additionally, we will be happy to receive any constructive feedback on the API/documentation, as this is constantly being updated and enhanced.
