Hello.
I'm a newbie. I'm following the instruction. My app doesn't show any exchanges, so I couldn't press subscribe. Can you tell me some reasons and solutions for my problem?

Started a new unity project today and stumbled into this same bug. The readme for this project mentions that this package was made due to certain constraints in the development environment for unity back in 2016-2017, including being restricted to .NET Framework 3.5 while RabbitMQ client continued its support onwards. If you are using a current version of Unity (at time of writing, 2018.3 is the stable release), then you are no longer constrained to .NET Framework 3.5 and can nuget the current version of RabbitMQ client.

If the above solution sounds applicable, then here is a link to another speed bump. Unity rebuilds C# solution and project files, so some steps must be taken in order for unity to not forget that you have installed nuget packages, like the RabbitMQ.Client. I hope it helps!
