I see that you are following our knowledge base article recommendations. I will need your assistance as I cannot investigate without some additional information. Can you provide a sample application that demonstrates the problem so that I can direct my efforts to the right path? I would mostly welcome the stack trace as the null reference exception message is quite common. Are you trying to deploy the application or are you facing the problem during the development phase? You have provided a screenshot of the exception but can you also show the full code snippet that is displayed on the error page? Everything you send us is fully confidential and will be used for testing purposes only.
I am looking forward to hearing from you.
