Re-target .NET Core to net471, net 472

It looks like Microsoft.AspNetCore.App and Microsoft.AspNetCore.All packages only work with the netcoreapp2.0 or netcoreapp2.1 version.

Wanting to target .NET Framework i.e. net471, net472, you have to remove these packages and manually add the references.

In my case, I removed Microsoft.AspNetCore.App and added references as below.

<PackageReference Include="Microsoft.AspNetCore" Version="2.1.1" />
<PackageReference Include="Microsoft.AspNetCore.Hosting.WindowsServices" Version="2.1.1" />
<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.1.1" />
<PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.1.1" />
<PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="2.1.1" />
<PackageReference Include="Microsoft.Extensions.Logging.EventLog" Version="2.1.1" />
<PackageReference Include="Microsoft.Extensions.Options" Version="2.1.1" />

Hung Quach's answer is right 99% right. However I found it was missing two packages. So below is the full .csproj including the two missing project refs:

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net472</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.CookiePolicy" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Hosting.WindowsServices" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.HttpsPolicy" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.1.1" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="2.1.1" />
    <PackageReference Include="Microsoft.Extensions.Logging.EventLog" Version="2.1.1" />
    <PackageReference Include="Microsoft.Extensions.Options" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.1.2" PrivateAssets="All" />
  </ItemGroup>

</Project>
