Hi Connor,
we released a blogpost and a video walkthrough last week, which should contain all the information you need: https://www.elastic.co/blog/elastic-apm-dot-net-agent-preview-released.
Btw. this is a really good feedback! We should add link to the NuGet packages and a short how-to about how to install into the documentation. I'll do it soon!
Let me know if you have any further questions.
Regards,
Greg
