Hi @Mizux , when do you plan to publish nuget packages?

[Mizux]

Tomorrow morning, at home today so I can't upload them (forget my yubikey at office -_-).
BTW you can find them on the release page, dl them in a directory and tweak you .csproj to find them...

<PropertyGroup> 
 <RestoreSources>local_path_to_downloaded_packages_directory;$(RestoreSources);https://api.nuget.org/v3/index.json</RestoreSources>
</PropertyGroup>

EDIT: somehow manage to upload them, feedback welcome !
