Paket fails to install nugets with paths longer than MAX_PATH

Description

paket restore fails with PathTooLong when installing the package runtime.opensuse.13.2-x64.runtime.native.System.Security.Cryptography.OpenSsl. This package is included by NETStandard.Library package

This bug seems to have been addressed in #949 but this seems another use case that is not handled correctly.

Repro steps

1. Create an empty project in a directory path long enough eg: C:\longomatch-build_windows_windows_x86\sources\windows_x86\lm-protected-git-master\

2. Create a packet.dependencies with the package NETStandard.Library

3. Run paket install

Expected behavior

The command detects that the path is too long and shortens the package ID

Actual behavior

The command fails with PathTooLong

Known workarounds

None

Is this problem related to the .NET framework used ? In this case, using .NET framework version >= 4.6.2 should solve this, as MAX_PATH limitation seems to be finally fixed.

Thanks for the advice! I’m targeting .NET 5, soon to be .NET 6, with no odd custom references, so this worked just fine for me.
