1. After upgrading the unit test vulnerability nugets,
   and changing to X64, I was left with:

Description: Microsoft.Extensions.DependencyInjection.Abstractions doesn't support net6.0. Consider updating your TargetFramework to netcoreapp3.1 or later

Project: Gui (net6.0)

File: C:\Users\alans.nuget\packages\microsoft.extensions.dependencyinjection.abstractions\6.0.0\buildTransitive\netcoreapp2.0\Microsoft.Extensions.DependencyInjection.Abstractions.targets

Line: 4

How can I build the utility?

2. Also the built site you mention does not have a downloadable on it. Is there anyplace else I can download it from?
