How to build an F# project via a .fsproj file?

I have a single F# file which I build so far via

fsc --standalone Foo.fs

into a single executable file which I can distribute to others who have not installed the F# toolchain.

Now I thought I move to a .fsproj file which scales better the more files I add to my project. Consider the following .fsproj file:

<?xml version="1.0" encoding="utf-8"?>
<Project Sdk="FSharp.NET.Sdk;Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="FSharp.NET.Sdk" Version="1.0.*" PrivateAssets="All" />
    <PackageReference Include="FSharp.Core" Version="4.5.*" />
    <Compile Include="Foo.fsx" />
  </ItemGroup>
</Project>

If I run dotnet build in a directory which contains both files, then I get the following output:

C:\Users\BillGates\.nuget\packages\fsharp.net.sdk\1.0.5\build\FSharp.NET.Core.Sdk.targets(170,9): error MSB6006: "dotnet.exe" exited with code -2147450730. [C:\temp\Foo.fsproj]

Searching for the error code -2147450730 did not help me. Any idea what is wrong with my setup? Any hints how to build a stand alone executable file from a F# file?

I'm using the following .NET versions:

dotnet --info
.NET Core SDK (reflecting any global.json):
 Version:   2.1.401

DO not use FSharp.NET.Sdk with any recent tooling. It was an intermediate package as long as F# was not in the box. Nowadays F# is in the box and the following should give you a working version:

dotnet new -lang f# dotnet build
