Please use NuGet correctly
Your NuGet packages have several problems.
1. You take binary dependencies on other things which are available via NuGet, but you're shipping those binaries yourself. You should be taking a package dependency instead, so that things can be referenced and versioned correctly.
2. Your "Couchbase with Logging" package should be an additive package that takes a package dependency on your "Couchbase" package, rather than shipping an entirely separate copy of the assembly. This causes linking conflicts.
