I want to be able to pass in an object like HttpRequestMessage into log messages only store the information that is relevant - I also don't want to have extract the wanted information every time I write to the log as there would be a lot of duplicated code.

Also worth noting is that HttpRequestMessage as a property causes a StackOverflowException.

I'm thinking something like this (with a little more polish):
