I can totally understand wanting to watch the maturity of a project first before including/promoting it. Either way I just wanted to let others know it exists.
I agree having to use an outdated client library was far from ideal. Unity definitely has an upgrade to .NET 4.6 in the "research" phase on their product roadmap.
I think part of the problem is that they forked Mono long ago and keeping it up to date is not trivial at this point.
A lot of headaches should disappear once they are able to get everything moved to more contemporary versions.
I'm hoping it will happen by the end of this year, but who knows.
When using the UWP build target for Unity they are already using a subset of 4.5 since UWP has very specific requirements.
They also seem to be partnering more and more with Microsoft, so I'm hoping that relationship continues to bear fruit.
I would definitely have used the latest client library had it been possible. Nevertheless I think the demand for Unity + AMQP will only be in growing
as time goes on.
Thanks for checking out the project.
