I'll look into it.

What platform? The debugger should work. Does the IDE indicate that it
was able to connect?

They're in Engine\Plugins\XamarinUE4\Patches

You'll have to manually edit the fsproj file to do something similar
to what the csproj does

Notably, at the top:

  <Import Project="..\Xamarin.UE4.generated.props" />

Then set the output path for all configurations:


And finally the targets:

  <Import Project="$(MonoUE4RuntimePluginLocation)\MSBuild\Xamarin.UE4.CSharp.targets"

You'll have create an FSharp equivalent of the targets but it should
be pretty simple since they just set a couple of properties then
import the language targets and some language-agnostic UE targets.
