nuGet无法在Visual Studio中安装第二个API

Question

I'm creating a C# program that needs to access both the Google drive and sheets API. When I install the first API(Drive) with the NuGet Console it successfully installs and it allows me to use it fine. The problem, however, lies with installing the second API. When I type in the command to install the Sheets API

Install-Package Google.Apis.Sheets.v4

it returns the following error message:

 Attempting to gather dependencies information for package 
 'Google.Apis.Sheets.v4.1.29.2.1002' with respect to project    
 'CSIBriarcliffAppUpdater', targeting '.NETFramework,Version=v4.5.2'
  install-package : An error occurred while retrieving package metadata

For some reason, the second API fails to install. I've recreated the project tons of times and every time I try to install a second API, it always returns this error message.

Answer 1

The reason I was getting an error is that my NuGet was outdated. For some reason VS doesn't notify you, so I went to Tools>Extensions and Updates and selected NuGet and updated it. As soon as I tried again everything worked perfectly.
