The specified path, filename, or both are too long

After moving my projects to .net core 3.0 i started getting te following error from within visual studio:

Error Failed to fetch results from V2 feed at 'http://****:8624/nuget/Dea/FindPackagesById()?id='runtime.fedora.24-x64.runtime.native.System.Security.Cryptography.OpenSsl'&semVerLevel=2.0.0' with following message : The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

Working w/ long paths is tough, and requires specialized Win32 API calls. Maybe we missed one, maybe NuGet or VS missed one.

Is this an error on the ProGet server? I.e. does its how up in Admin > DIagnostic Center? Can you pull this package to ProGet service, and download it from WebUI?

If you're running on Windows 2016 or newer, have you tried this?
