Of course you can manage the referencing of the specific version -noref switch:
//css_nuget Seq.Client.NLog
//css_nuget -noref -ng:"–Version 3.1.0" NLog
//css_ref %css_nuget%\NLog\NLog.3.1.0\lib\net40\NLog.dll
However this will not trigger the download of that specific version if some of NLog versions is already downloaded. Thus you will need to clean your NuGet directory to force the download.
Format:
//css_nuget [-noref] [-force] [-ver:<version>] [-ng:<nuget arguments>] package0...[,packageN];
Examples:
//css_nuget -force cs-script;
//css_nuget -ver:4.1.2 NLog
//css_nuget -ver:"4.1.1-rc1" -ng:"-Pre -NoCache" NLog
Can you please verify the fix before it goes fully official.
Thank you
