  12   This target file contains the NuGet Restore target for walking the project and reference graph
  13   and restoring dependencies from the graph.
  14
  15   Ways to use this targets file:
  16   1. Invoke it directly and provide project file paths using $(RestoreGraphProjectInput).
  17   2. With a solution this may be used as a target in the metaproj.
  18   3. Import the targets file from a project.
  19
  20   Restore flow summary:
  21   1. Top level projects (entry points) are determined.
  22   2. Each project and all of its project references are walked recursively.
  23   3. The project is evaluated for each $(TargetFramework). Items are created
  24      for project properties and dependencies. Each item is marked
  25      with the project it came from so that it can be matched up later.
  26   4. All restore items generated by the walk are grouped together by
  27      project and convert into a project spec.
  28
  29   The result file contains:
  30   1. A list of projects to restore.
  31   2. The complete closure of all projects referenced (Includes project references that are not being restored directly).
  32   3. Package and project dependencies for each project.
  33   4. DotnetCliTool references
