I think you will have issues with 4.7.1 and .netstandard in general, not F# related.

But regarding this bug, it has been fixed. https://github.com/Microsoft/visualfsharp/pull/4096 . On next vs release it should be resolved.

hoetz commented 6 years ago

Glad to see it's fixed. Since net471 has built in support for netstandard20 I hope there won't be any problems.

cartermp commented 6 years ago

@hoetz See here for more info: https://github.com/dotnet/standard/issues/481

In short, you will likely run into problems. However, none are F#-related as far as we can tell. Given that the issue with project references in the VS UI is fixed, I'll close this out.

ctaggart commented 6 years ago

Essentially net471 is broken. Don't install it. It broke this scenario for everyone on AppVeyor.
