Could not detect any platforms from 'Xamarin.*' messages.

[halcwb]

Description

I did a fresh install of Fable, all the way down from brew on El Capitan, including yarn and dotnet. Mono version 4.4.0 pre-installed.

Repro steps

Install a new fable project following the instructions on the fable website. Build the project using dotnet restore and dotnet fable yarn-run build.

Expected behavior

Installation of dependencies.

Actual behavior

A lot of messages like:

Could not detect any platforms from 'Xamarin.*'

Known workarounds

Ignore the messages.

could you please copy the exact messages?

yeah it's becoming a bit annoying ;-)

Best think would be to add them and extend the parser ;)

[matthid]

Just an addition: imho just removing the warning is not an option. Paket needs to tell you if it cannot understand the supported platforms otherwise user has the expectation that all platforms work as expected. Additionally it might change the used references from what nuget might do.

I didn't meant to remove the warning. we should implement it properly
