With .NET Core 3 a template 'dotnet new worker' was created that allows services to be created. The template currently only works to create C# code so this snippet shows how I have translated the C# into F# and the steps needed to create the service.
dotnet new console -lang F# -o FsharpService
dotnet add package Microsoft.Extensions.Hosting.WindowsServices
dotnet add package System.Net.NameResolution
Update the program.fs as shown below and then build and install the service
dotnet publish -r win-x64 -c Release /p:PublishSingleFile=true /p:PublishTrimmed=true -o "./published"
sc create fSharpService binPath= "<
