NServiceBus internalize both the raven client and json.net. That is why those attributes don't work(they are essentially different types since we merge with the internal flag). The workaround is to use the core only version of nsb that isn't merged.
That said I'm curious why you need those extra properties?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
