There is an old version of HtmlAgilityPack.dll in the package

[ghnz]

When I install The CssSelectors package after installing a later version of HtmlAgilityPack the HtmlAgilityPack.dll is overwritten with the old version.

As HtmlAgilityPack.CssSelectors is dependent on HtmlAgilityPack the HtmlAgilityPack.dll does not need to be in the lib > net45 folder.

I can confirm this behaviour.
