dotnet nuget push gives 401, but nuget.exe push succeeds

Question

I've created a feed in Azure Artifacts, to which I want to publish Nuget packages. I have generated a Personal Access Token with the correct scope.

Running this command succeeds:

> nuget.exe  push -Source "myAzureFeed" -Apikey $(cat apikey) .\bin\Debug/MyPackage1.2.3.nupkg

Whereas, this command:

> dotnet nuget push .\bin\Debug\MyPackage.1.2.3.nupkg -s "myAzureFeed" -k $(cat apikey)

Gives me 401

PS D:\NuGet\create-package\using-dotnet-cli> dotnet nuget push .\bin\Debug\MyPackage.1.2.3.nupkg -s myAzureFeed -k $(cat apikey)

Why does nuget.exe push succeeds and dotnet nuget push fails?

Why does nuget.exe push succeeds and dotnet nuget push fails?

There's already a GitHub ticket talking about this. See JeremyTCD's comment:

--api-key works for some feeds (eg Nuget.org) but not for others (eg Azure Artifacts feeds). For the latter kind of feed you need to specify password. Unfortunately password isn't accepted by the dotnet nuget or nuget CLIs so you have to set it in a nuget.config. Easiest way to update nuget.config is nuget sources add....

The dotnet nuget push command pushes a package to the server and publishes it. The push command uses server and credential details found in the system's NuGet config file or chain of config files. See dotnet nuget push for details.

So, before using the dotnet nuget push command, you should add the credential and API key in NuGet.config as below commands:

nuget sources Add -Name "mysource" -Source "https://XXX.pkgs.visualstudio.com/_packaging/YYY/nuget/v3/index.json" -username name -password PAT nuget setapikey mykey -source mysource 

Then push the NuGet package through the dotnet nuget push command:

dotnet nuget push packagename.nupkg --source mysource --api-key mykey

You can also reference the samples instructed here: Publish packages from external sources to do that by running dotnet nuget comamnds.
