Xamarin, UWP and a dependence

I thought my problem was very simple to resolve but it isn't. I'm creating some new components for Xamarin. I have a main Xamarin project where I'm testing my components.

My components are a main portable project and for each platform there is specific implementation.

The implementation for UWP generates a compatibility error

Project PSC.Xam.Controls.BindableRadioButton.UWP is not compatible with uap10.0 (UAP,Version=v10.0). Project PSC.Xam.Controls.BindableRadioButton.UWP supports: uap10.0.10240 (UAP,Version=v10.0.10240) One or more projects are incompatible with UAP,Version=v10.0.

NuGet package restore failed.

I checked the configuration of UWP main project and the implementation project and both are the same settings.

UWP Implementation Settings

In the implementation project, I have a reference to the portable project and its settings are:

If I deploy the project and run it, it seems working fine on my desktop.

Also, I receive two other errors:

Duplicate Entry

0xdef00532 - Conflicting values for resource 'Files/Xamarin.Forms.Platform.UAP/TabbedPageStyle.xbf' GENERATEPROJECTPRIFILE

I checked my Package.appxmanifest and Dependencies is as requested.

  <Dependencies>
    <TargetDeviceFamily Name="Windows.Universal" 
                        MinVersion="10.0.0.0" 
                        MaxVersionTested="10.0.0.0" />
  </Dependencies>

In order to use .NET Standard 2.0 in UWP, you need to target Fall Creators Update (FCU) as the minimum version of your UWP project. That’s because .NET Standard 2.0 contains many APIs that require FCU to make them work in the context of the UWP execution environment, specifically AppContainer.

Find project.json file and replace "uap10.0" with "uap10.0.10586"
