Ask questionsCan't use `dotnet add package` with a private repository (basic authentication)

Details about Problem

  • dotnet --version
    • 1.0.1
  • dotnet
    • 1.1
  • NuGet
  • MacOS Sierra
    • 10.12.4

Steps to reproduce

  1. Create a private NuGet repository (in my case using AppVeyor)
  2. Add it as a source:
nuget sources add -Name xxx -Source -Username -Password xxx
  1. Prove that it's possible to list packages:
nuget list -s xxx
Using credentials from config. UserName:
my.nuget.package 1.0.1

4 Attempt to add the private NuGet package to a dotnet project using the CLI:

dotnet add package -s my.nuget.package


For the command to add the NuGet package to the project.


Got a message saying that it couldn't authenticate.
