    </PackageReference>
    <PackageReference Include="Forms.Controls.FlexButton" Version="0.11.0" />
    <PackageReference Include="Microsoft.AppCenter" Version="3.0.0" />
    <PackageReference Include="Microsoft.AppCenter.Analytics" Version="3.0.0" />
    <PackageReference Include="Microsoft.AppCenter.Crashes" Version="3.0.0" /> …
