Hello,
It seems that Dynamicweb.Admin.dll is not include the in Nuget Package if you have targeted .Net 4.6
First screenshot is dw 9.6.11.
Second is dw 9.7.1
Is does exist in the "\packages\Dynamicweb.Admin.9.7.1\lib\net472" but since my project is targeting 4.6, it does get copied (I assume).
Could be awesome to include it in net46 :-)
