thanks for you interest!
Sorry about MiniChat compilation issues.
MiniChat has been updated to demonstrate discovery capabilities of Zyan, but discovery feature is not yet released.
I'm going to publish Zyan version 2.6 in the nearest future, and this version will include service discovery.
is there a comprehensive doc for what those different debug/3/4 are?
These folders are for binaries targeting different versions of .NET framework.
Debug3 — .NET 3.5, Debug 4 — .NET 4.0, Debug — most up-to date .NET 4.5 version.
Would you recommend working with the sources or the nuget package?
Yes, I'd recommend using the latest sources until v2.6 is released.
The latest sources include lots
of bugfixes compared to v2.5.
