Can't restore with NuGet.exe (error running the CredentialProvider) about artifacts-credprovider HOT 4 CLOSED

Well it looks like this specific error happens because I passed the -verbosity argument to NuGet.exe call and it also calls the CrendentialProvider with that.

But the problem is still here: if I do not use the -verbosity argument the warning about credential plugin model being deprecated still shows up and then I get a 401 Unauthorized

from artifacts-credprovider.

So, more news on this.

If I try to call the CredentialProvider directly it seems to work, using this command line:

CredentialProvider.Microsoft.exe -uri https://pkgs.dev.azure.com/<project>/_packaging/<feed>/nuget/v3/index.json -nonInteractive

I actually get a response with a username and a password.

However, through nuget.exe, I am getting the following error:

WARNING: The credential plugin model used by 'C:\svn\trunkrepo\ServiceStudio..\Commons\ThirdParty\AzureCredentialsProvider\plugins\netfx\CredentialProvider.Microsoft\CredentialProvider.Microsoft.exe' is deprecated. Please contact the provider of the plugin for an alternative. More information about the recommended plugin model can be found at 'https://aka.ms/nuget-cross-platform-authentication-plugin'.
Credential plugin C:\svn\trunkrepo\ServiceStudio..\Commons\ThirdParty\AzureCredentialsProvider\plugins\netfx\CredentialProvider.Microsoft\CredentialProvider.Microsoft.exe returned Success with an unreadable payload.

NUGET_CREDENTIALPROVIDERS_PATH is used for plugins supporting the old plugin model: https://docs.microsoft.com/en-us/nuget/reference/extensibility/nuget-exe-credential-providers.

This is a V2 style provider:

https://docs.microsoft.com/en-us/nuget/reference/extensibility/nuget-cross-platform-plugins#plugin-installation-and-discovery

Basically, don't use the environment variable. If you already have the plugin in the netfx folder, it should pick it up automatically.

Closing as not a bug. @Diogomrol please let us know if you're still having issues, but hopefully Nikolche's guidance above helped.
