Minimal VS install has broken NuGet UI

[zivkan]

Withthe VS 16.3 preview, if you install just the shell, no workloads selected, then run VS, the Package Manager Console can be opened, but the host never finishes initializing. Also, if you go to tools->Options, if you select either of the NuGet pages you get an error.

From Jitin John on DevCom:

What steps will reproduce the problem?
Open VS 2019 without any solution
Go to Nuget Package Manager Settings
What is the expected output? What do you see instead?
Expected: Settings of nuget sources
Actual: An error occurred loading this property page

Please provide any additional information below.
This problem started soon after using VS2019

Workaround: Install one Workload that depends on NuGet component, named Microsoft.VisualStudio.Component.NuGet, documented here

[zivkan]

Another instance: https://developercommunity.visualstudio.com/t/error-setting-up-nuget-package-manager/1457437?from=email&viewtype=all#T-ND1459974

From the ComponentModel cache error file:

NuGet.PackageManagement.VisualStudio.NuGetProjectFactory.ProjectServiceAccessor: expected exactly 1 export matching constraints:
    Contract name: Microsoft.VisualStudio.ProjectSystem.IProjectServiceAccessor
but found 0.
   part definition NuGet.PackageManagement.VisualStudio.NuGetProjectFactory

We need to ensure that the settings page doesn't need to use the project system APIs, since the .NET project system might not be installed.
