NuGet.targets
WARNING: DO NOT MODIFY this file unless you are knowledgeable about MSBuild and have
created a backup copy. Incorrect changes to this file will make it
impossible to load or build your projects from the command-line or the IDE.
Copyright (c) .NET Foundation. All rights reserved.
***********************************************************************************************
This target file contains the NuGet Restore target for walking the project and reference graph
and restoring dependencies from the graph.
Ways to use this targets file:
1. Invoke it directly and provide project file paths using $(RestoreGraphProjectInput).
2. With a solution this may be used as a target in the metaproj.
3. Import the targets file from a project.
Restore flow summary:
1. Top level projects (entry points) are determined.
2. Each project and all of its project references are walked recursively.
3. The project is evaluated for each $(TargetFramework). Items are created
for project properties and dependencies. Each item is marked
with the project it came from so that it can be matched up later.
4. All restore items generated by the walk are grouped together by
project and convert into a project spec.
The result file contains:
1. A list of projects to restore.
2. The complete closure of all projects referenced (Includes project references that are not being restored directly).
3. Package and project dependencies for each project.
4. DotnetCliTool references
