PlatformNotSupportedException: Microsoft.Data.SqlClient is not supported on this platform

问题

What might be the error? I looked at similar problems, downgrading the version to 2.0 is workaround but this is not true

DAL.dll

<ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.4" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Proxies" Version="3.1.4" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.1.4" />
  </ItemGroup>

UIWEBAPP.dll

<ItemGroup>
    <PackageReference Include="CKEditor" Version="3.6.4" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.4" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Proxies" Version="3.1.4" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.1.4" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="3.1.3" />
    <PackageReference Include="Newtonsoft.Json" Version="12.0.3" />
  </ItemGroup>
