Describe the bug
After updating VS2019 to 16.8, the Windows Community Toolkit solution is no longer building.
The build is failing at the nuget restoration step with:
1>------ Rebuild All started: Project: Microsoft.Toolkit, Configuration: Debug Any CPU ------
Error occurred while restoring NuGet packages: Invalid restore input. Duplicate frameworks found: 'netstandard1.4, uap10.0.17763, uap10.0.17763, net461, netcoreapp3.1'. Input files: C:\[...]\WindowsCommunityToolkit\Microsoft.Toolkit.Uwp.Notifications\Microsoft.Toolkit.Uwp.Notifications.csproj.
1>Microsoft.Toolkit -> C:\[...]\WindowsCommunityToolkit\Microsoft.Toolkit\bin\Debug\netstandard2.1\Microsoft.Toolkit.dll
1>Microsoft.Toolkit -> C:\[...]\WindowsCommunityToolkit\Microsoft.Toolkit\bin\Debug\netstandard1.4\Microsoft.Toolkit.dll
1>Microsoft.Toolkit -> C:\[...]\WindowsCommunityToolkit\Microsoft.Toolkit\bin\Debug\netstandard2.0\Microsoft.Toolkit.dll
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
- Is this bug a regression in the toolkit? If so, what toolkit version did you last see it work:
Steps to Reproduce

Steps to reproduce the behavior:
- Update VS2019 to 18.8.1
- Open the solution

Additional context
The problem seems to be related to the Microsoft.Toolkit.Uwp.Notifications.csproj
Removing the native target from the TargetFrameworks list of the project fix the nuget restore operation but then the build is failing later with symbols not being found.
I changed
<TargetFrameworks>netstandard1.4;uap10.0;native;net461;netcoreapp3.1</TargetFrameworks>
to
<TargetFrameworks>netstandard1.4;uap10.0;net461;netcoreapp3.1</TargetFrameworks>
