One needs to enable long path support on those systems by setting a group policy.

Steps:

  1. Launch Group Policy Editor - Type "Edit group policy" in the Start search bar or Run "gpedit.msc" from the Run command (Windows-R).
  2. In the Local Group Policy Editor, enable "Local Computer Policy/Computer Configuration/Administrative Templates/All Settings/Enable Win32 long paths".

Note

Enabling Other NuGet Tools to Support Long Paths

  • Dotnet CLI supports long paths regardless of the operating system or version.
  • Visual Studio or msbuild -t:restore does not yet support long paths.
  • Software that uses NuGet Libraries to execute restore and other commands, will support long paths on the same systems that NuGet.exe works on, if they also set longPathAware in their windows manifest and configure UseLegacyPathHandling to false via App.Config See more information
