Self-contained linux app missing libhostfxr.so

Using https://dotnetcli.blob.core.windows.net/dotnet/Sdk/master/dotnet-sdk-latest-linux-x64.tar.gz

RUN dotnet restore --runtime linux-x64 --configfile /app/Nuget.Config RUN dotnet publish -c Release -f netcoreapp3.0 --self-contained --runtime linux-x64 --no-restore -o /out

csproj is roughly

  <PropertyGroup>
    <TargetFrameworks>netcoreapp3.0</TargetFrameworks>
    <OutputType>Exe</OutputType>
    <RuntimeIdentifiers>win10-x64;linux-x64</RuntimeIdentifiers>
  </PropertyGroup>

    <ItemGroup>
      <FrameworkReference Include="Microsoft.AspNetCore.App" />
    </ItemGroup>

# ./Watchdogs
A fatal error occurred, the required library libhostfxr.so could not be found.
If this is a self-contained application, that library should exist in [/app/Watchdogs/].
If this is a framework-dependent application, install the runtime in the default location [/usr/share/dotnet] or use the DOTNET_ROOT environment variable to specify the runtime location.

# ldd ./Watchdogs

        /lib64/ld-linux-x86-64.so.2 (0x00007ff3e5b0e000)

I think this is a recent development. The previous sdk nightly worked fine. There are no *.so files in the output directory

Using that other build seemed to fix it. Thanks.

@nguerrera since it sounds like you have a working theory, feel free to assign to you as I simply self-assigned so I could poke it with a stick tomorrow.
