This directory contains code that is copied from https://github.com/NuGet/NuGet.Client/tree/dev/src/NuGet.Core/NuGet.Frameworks, with the namespaces changed
and class visibility changed. This is done to ensure we are providing the same functionality as Nuget.Frameworks, without depending on the package explicitly.

The files in this folder are coming from tag $VersionTag, on commit $commit.

To update this code, run the script in: $($PSCommandPath -replace [regex]::Escape($root)) , with -VersionTag <theDesiredVersion>.
