Build via: dotnet publish -c Release -o ..\OutputAsp2.1.0 --self-contained

Following csproj -> empty WebApplication project with properties:

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

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <RuntimeIdentifier>win10-x64</RuntimeIdentifier>
    <!-- <RuntimeFrameworkVersion>2.1.0</RuntimeFrameworkVersion> -->
  </PropertyGroup>

  <ItemGroup>
    <Folder Include="wwwroot\" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
	<!-- <PackageReference Include="Microsoft.AspNetCore.App" Version="2.1.0" /> -->
  </ItemGroup>

</Project>

Four combinations:

1. Default, like above:

  ".NETCoreApp,Version=v2.1": {
      "WebApplication1/1.0.0": {
        "dependencies": {
          "Microsoft.AspNetCore.App": "2.1.5",
          "Microsoft.NETCore.App": "2.1.5"
        },
        "compile": {
          "WebApplication1.dll": {}
        }
      }

2. Enable RuntimeFrameworkVersion

    ".NETCoreApp,Version=v2.1/win10-x64": {
      "WebApplication1/1.0.0": {
        "dependencies": {
          "Microsoft.AspNetCore.App": "2.1.5",
          "Microsoft.NETCore.App": "2.1.0"
        },
        "runtime": {
          "WebApplication1.dll": {}
        }
      }

3. Enable RuntimeFrameworkVersion and ASP.NET Core App Version

    ".NETCoreApp,Version=v2.1": {
      "WebApplication1/1.0.0": {
        "dependencies": {
          "Microsoft.AspNetCore.App": "2.1.0",
          "Microsoft.NETCore.App": "2.1.0"
        },
        "compile": {
          "WebApplication1.dll": {}
        }
      }

4. Enable only ASP.NET Core App Version

    ".NETCoreApp,Version=v2.1": {
      "WebApplication1/1.0.0": {
        "dependencies": {
          "Microsoft.AspNetCore.App": "2.1.0",
          "Microsoft.NETCore.App": "2.1.5"
        },
        "compile": {
          "WebApplication1.dll": {}
        }
      }
