We're converting some code from using the old client to the new client.

The new version of `UpdateRequest`, to pick an example, now has type parameters `TDocument` and `TPartialDocument` ... but I can't find out (after a couple of hours of reading documentation and searching) what these are, where I'm supposed to get them from, etc?

Well, if I set them to `<Object, Object>` then things work ... but ... ???
