Shared project UWP issues in VS 2022 Preview 3 and 4

[xperiandri]

This is my workaround that allows temporarily fixing all the issues related to spared project usage in UWP

  <!--<Import Project="..\CarWashScanner.Shared\CarWashScanner.Shared.projitems" Label="Shared" Condition="Exists('..\CarWashScanner.Shared\CarWashScanner.Shared.projitems')" />-->
  ...
  <ItemGroup>
    <ApplicationDefinition Include="..\CarWashScanner.Shared\App.xaml">
      <SubType>Designer</SubType>
      <Generator>MSBuild:Compile</Generator>
    </ApplicationDefinition>
    <Page Include="..\CarWashScanner.Shared\**\*.xaml" Exclude="..\CarWashScanner.Shared\App.xaml">
      <Link>%(RecursiveDir)%(Filename)%(Extension)</Link>
      <SubType>Designer</SubType>
      <Generator>MSBuild:Compile</Generator>
    </Page>
    <Compile Include="..\CarWashScanner.Shared\**\*.cs" Exclude="..\CarWashScanner.Shared\**\*.xaml.cs">
      <Link>%(RecursiveDir)%(Filename)%(Extension)</Link>
    </Compile>
    <Compile Include="..\CarWashScanner.Shared\**\*.xaml.cs">
      <Link>%(RecursiveDir)%(Filename)%(Extension)</Link>
      <DependentUpon>$([System.String]::Copy('%(Filename)').TrimEnd('.cs'))</DependentUpon>
    </Compile>
  </ItemGroup>
  <Target Name="ReplaceXbfFiles" AfterTargets="Prep_ComputeProcessXamlFiles" BeforeTargets="CopyGeneratedXaml">
    <ItemGroup>
      <TempXbfSrc Include="@(GeneratedXamlSrc->Replace('..\CarWashScanner.Shared\',''))" />
      <TempXbfDest Include="@(GeneratedXamlDest->Replace('..\CarWashScanner.Shared\',''))" />
      <GeneratedXamlSrc  Remove="@(GeneratedXamlSrc)"  />
      <GeneratedXamlDest Remove="@(GeneratedXamlDest)" />
      <GeneratedXamlSrc  Include="@(TempXbfSrc)"  />
      <GeneratedXamlDest Include="@(TempXbfDest)" />
      <TempXbfSrc  Remove="@(TempXbfSrc)"  />
      <TempXbfDest Remove="@(TempXbfDest)" />
    </ItemGroup>
  </Target>

This is a visual studio 17.2 Preview 3 issue. Looks like it broke some of the properties used by Shared projects, causing an error similar to this:

C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\XamlCompiler\Microsoft.Windows.UI.Xaml.Common.targets(580,5): 
error MSB3030: Could not copy the file "obj\x64\Debug\....\MyProject.Shared\MainPage.xbf" because it was not found. 

A simpler temporary workaround is to add this to the UWP, Android, iOS or WebAssembly csproj:

<PropertyGroup>
   <SynthesizeLinkMetadata>true</SynthesizeLinkMetadata>
</PropertyGroup>
