Unable to compile after upgrade to Windows 10 1903

[ToreDemant]

After upgrading to Windows 10 1903 I am no longer able to compile this example.

I am getting the following warnings:
The referenced component 'Windows.Data' could not be found.
The referenced component 'Windows.Foundation' could not be found.
The referenced component 'Windows.UI' could not be found.

And errors where code is dependent on the above assemblies.

These files were earlier in system32 but seems to have been removed from 1903. I have not been able to fin a nuget package that includes them.

I also updated to Visual Studio 16.0.3 to 16.1.1 but I don't think that this is the problem.
I have also been having problems building the progress example on a Windows 2016 build server: https://stackoverflow.com/questions/55899493/toastnotification-does-not-contain-a-definition-for-data-on-windows-server-2

I have tried on a machine with VS 16.0.2 / Windows 1903 - same build failures. Afterwards I downgraded the box to Windows 1809 and the project build successfully again.

I am facing the same issue. Is there any solution beside downgrading windows?

I am currently still on 1809, but I far as I remember then I got it working on 1903 by adding the following references manually to the project file:

<Reference Include="Windows.Foundation.FoundationContract">
  <HintPath>C:\Program Files (x86)\Windows Kits\10\References\10.0.17763.0\Windows.Foundation.FoundationContract\3.0.0.0\Windows.Foundation.FoundationContract.winmd</HintPath>
</Reference>
<Reference Include="Windows.Foundation.UniversalApiContract">
  <HintPath>C:\Program Files (x86)\Windows Kits\10\References\10.0.17763.0\Windows.Foundation.UniversalApiContract\7.0.0.0\Windows.Foundation.UniversalApiContract.winmd</HintPath>
