@TheCakeIsNaOH @AdmiringWorm I have added this issue to a new 2.0.0 milestone, but I am now wondering if this needs to be a 2.0.0 and not just a 1.2.0. Thoughts? My thoughts here being that Chocolatey GUI already has a requirement for .NET Framework 4.8.

Just spoken with @TheCakeIsNaOH about this, and we agree that this will be a breaking change to Chocolatey GUI, so the next version will be 2.0.0

If we start taking a minimum dependency on Chocolatey v2.0.0, I agree this will be a breaking change.
