Hi Ron,
It is not an older version. It is just a NuGet package update.
Both 3.5.0.0 and 3.5.0.2 packages have the same CSScriptLibrary.dll (v3.5.0). The actual difference is in the package metadata (e.g. Description) that I needed to make in order to fix the early packaging mistake.
The problem is that NuGet server does not allow updating the package without incrementing the version. At the same time incrementing the version of the assembly does not make any sense as there is nothing changed in it.
The issue is irrelevant now anyway as I just published CS-Script NuGet package v 3.5.3.0 containing CSScriptLibrary.dll v 3.5.3.0.
Thank you for your feedback,
