Convert to FAKE5

As a bonus would be great if the docs generation did not depend on net46

@et1975 Need some help if you have the time. Facing an odd issue in AppVeyor, but I am not having any .NET SDK installation-related issues on my machine (I'm on Windows 7).

Seems like every AppVeyor build is failing on installing the SDK. I tried updating to 2.1.300 in the hopes that it would succeed. I don't normally use AppVeyor and I'm having a hard time figuring out what is going on.

For the moment, I have reverted all references to SDK 2.1.4 (obviously still failing).

Ok, stopped and paid closer attention to the logs. Appears that the real failure point is restore. Trying some alternate syntax(es).

Well, this error is quite frustrating.

Fake.Core.BuildFailedException: Target 'Install' failed. ---> System.AggregateException: One or more errors occurred. ---> System.Exception: Start of process 'dotnet' failed. ---> System.ComponentModel.Win32Exception: ApplicationName='dotnet', CommandLine=' restore Fable.Elmish.fsproj ', CurrentDirectory='/home/travis/build/elmish/elmish/src', Native error= Cannot find the specified file

Not sure why it can't find the fsproj file, unless dotnet restore doesn't want the file name when restoring (something specific to Linux, as this is working just fine on Windows?).

Ok, after 4 tries, I think that the system cannot find dotnet (should have realized this earlier, but I was sure it couldn't find the fsproj) 🤦‍♂️

Working on that issue now.

@zakaluka Thanks for giving this issue a try.

For appveyor problem, can you try to use something equivalent to this one ?

I also added some comments in your current PR.

I just noticed appveyor hasn't built anything since we renamed the org. I updated the settings, let's hope it kicks in now.
Travis seems currently failing due to build documentation. That was always finicky, but I think there was an update for FSharp.Formatting that supports netcore.
Also, let's make the travis job easier, set dotnet arg, so it uses pre-installed dotnet instead of installing it on each build (as long as it matches global.json).

1. AppVeyor is successfully building now. For now, it is running the Build target.

2. Travis is giving a pretty odd error message. The specifics can be found in this log file. In short, the error states:

Could not find script './paket-files/Build/fsharp/FAKE/modules/Octokit/Octokit.fsx' in any paths searched. Searched paths:
["../../src/bin/Release/netstandard2.0"]

This error does not occur on AppVeyor, which seems to build just fine. I tried a few variations on the #load statement in build.fsx in an attempt to navigate to the file, but none of them seemed to succeed. Any idea what might be causing this?

@et1975 One note, I think we can't yet bootstrap FAKE using netcore runtime because we are using F#.Formatting which is running only for .Net I think.

Should this be closed since #149 was merged?
