How to Reference System. Management. Automation in A. Net Framework 4.7.2?

I started a new .NET Framework 4.7.2 library project. I need to automate PowerShell scripts, but the "framework" tab in Visual Studio's reference adding UI didn't list System.Management.Automation as an option. So I added a reference to this Nuget package:

Then with this code:

PowerShell ps = PowerShell.Create();
ps.AddScript(@"C:\ps\function.ps1");
ps.AddArgument(1);
ps.AddArgument(2);
Collection<PSObject> results = ps.Invoke<PSObject>();

I get this error about versions of a DLL which I did not directly reference:

Assembly 'System.Management.Automation' with identity 'System.Management.Automation, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' uses 'System.Linq.Expressions, Version=4.2.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' which has a higher version than referenced assembly 'System.Linq.Expressions' with identity 'System.Linq.Expressions, Version=4.1.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

I'm not sure how to resolve this, and I think maybe I approached adding my PowerShell automation library reference the wrong way. What's the right way to do this currently?

Before you point me at an old answer, I found a similar question about this which points to a different Nuget package, now marked "deprecated" and doesn't look official anyway. That makes me nervous.
