Microsoft.Web.LibraryManager.Build 2.0.76
VS 2017 15.9.11
ASP.NET Web Form project using 4.6.1

On some machine in our office using VS 2017, we can't build our ASP.NET project that has the "auto restore" enabled for LibMan.
Some machines with VS 2017 using the same project build fine.

What seems to be odd is that our ASP.NET project references "System.Net.Http Version 4.0.0.0" yet the LibraryManager is referencing "System.Net.Http Version 4.2.0.0".
I think this is either a bad reference pointing to a file not installed on users machines or not using the GAC version of System.Net.Http.

We get the following:
