Thank you for doing the clean up!

Question: Why did you remove this one?
It looks like it is out of place but it is maybe still useful?

[soujay]

@tamararivera - This is a duplicate link in the left nav. There is already a link for this under samples. I removed this as the one under samples is more appropriate place

• Samples - General- Unit Testing NServiceBus

This was probably deliberately put there. The history is that we used to have fluent style tests. During the transition, we put the sample up there to lead people towards using the AAA style tests. Now that the fluent API style is no longer supported, the sample up there is indeed "duplicated".

Fixing the redirects would be an important thing to do in this PR. Other than that, thanks for the nice cleanup!
