Thanks for opening this - I added 1 thing regarding Service.Resource which should be removed.

Additionally, we'd also need to adapt tests to cover this.

The rest looks good - nice catch! 👍

Service does not need to be set here. Two things to this:

1. According to the current spec Service.Resource should be just monodb. Spec here
2. There is a logic in Span.cs here which fills this.

So this should be removed.

[gregkalapos]

Nice - indeed, this should be mongodb.

This is done in #1677.
