    Hello,

    Welcome to Microsoft Q&A!

    @SmilingMoon You could try to add <Target Name="ResolvePackageDependenciesForBuild" /> this into the project file of the packaging project.

    Like this:

      <ItemGroup>  
        <ProjectReference Include="..\TestUWP\TestUWP.csproj" />  
      </ItemGroup>  
      <Target Name="ResolvePackageDependenciesForBuild" />  
    </Project>  
    

    After adding this, I could run your sample correctly without exceptions.

    Thank you.
