Hi Vitus,

Looking at the exception, I am not sure if this error is related to Telerik Platform or any of its services. Therefore, would please elaborate a bit more on the exact case and what you would like to achieve? What is the type of the application you are trying to run? Is it eventually an asp.net ajax project? If so, I would suggest you to look through the respective forum category. 

Regards,
