Thank you for writing.
I will need more context in order to be able to help you:
1. What is the version you use where you get the error.
2. How did the error appeared.
3. The type is in a namespace used for internal purposes, so what are you using this type for?
4. If possible, please get back to me with a sample or a code snippet where you use this type.
Once I have this information I will do my best to assist you in resolving the error you've got.
I am looking forward to your reply.
