Note that most of the forum threads are reviewed by Telerik representatives and sometimes we address the questions asked by our customers in the forums as well. However, a post in the forum doesn't guarantee you a response from the Telerik support team. Moreover, threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread.
As a gesture of good will, we will address this thread for you. Following the code snippets in the referred KB article, I have prepared a sample project for your reference. It seems to build successfully on my end with the latest version (2019.1 117). Please refer to the attached zip file.
I hope this information helps.
