dotnet-subset is a .NET tool that copies a subset of files from a repository to a directory.
The tool is mainly used in Dockerfiles to optimize the docker build caching for "dotnet restore" instructions.
For each required project, copies the NuGet lock file and support the NuGetLockFilePath property. See https://learn.microsoft.com/en-us/nuget/consume-packages/package-references-in-project-files#lock-file-extensibility.
Only copies files under the specified root, while maintaining their relative path to it.
