为解决方案文件夹外的项目设置NuGet包文件夹

Question

I have the following project structure:

• \\Root
  • \\SolutionFolder
    • \\App1
      • 📙 packages
      • Program.cs
      • App1.csproj
    • \\App1.sln
  • \\App2
    • 📗 packages
    • Program.cs
    • packages.config
    • App2.csproj

*Note: App2 project is referenced by App1.
My problem is that whenever I rebuild the solution, the \\packages folder containing nuget packages for App2 project, is added to \\App1 instead of \\App2 .
This is a problem because this App2 project is referenced by other solutions as well, not only from App1.
So it is important to have it's own \\packages folder and not to have a reference from App2 --> App1, since App2 is shared by other solutions as well.

Update: The App1 has its own nuget packages installed in it's own \\packages folder. I want a solution for keeping each project installing nuget packages in its own \\packages folder.

You can add NuGet.config file to your solution, which will change default path to the packeges folder:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <config>
    <add key="repositorypath" value="..\..\packages" />
  </config>
</configuration>

Of course you need to put a relative path which is correct in the specific solution. A solution-specific NuGet.Config file should be located within a .nuget folder in the solution.

Here: https://docs.nuget.org/ndocs/consume-packages/configuring-nuget-behavior you have a detailed description of this.
