Credential Provider + Linux + Rider

[kirill-d-lappo]

I am not sure if it is an issue at all and who is responsible for it, I am just making some notes on the issue I have run into.

Preparations

• linux distro (linux mint 21.1)
• Rider (2023.1.3)
• Azure Devops nuget feed

Problem:

Rider does not communicate with the Azure nuget feed, user can't see any packages from it.

At the same time dotnet restore works as expected.

Description

Rider logs contains the next error:

Seems like Rider uses credential provider binary directly to display packages.

But the plugin in artifacts is built for windows platform only.

Solution

Clone artifacts-credprovider repo and build the plugin manually for linux platform.

# after cloning and cd-ing into the repo

# the config in the repo contains a link to a private nuget feed
# but you can restore all dependencies via public nuget.org feed
# so just remove that private repo
rm ./nuget.config

pluginDir="$HOME/.nuget/plugins/netcore/CredentialProvider.Microsoft"

# clean up existing plugin
rm -rf "$pluginDir"

# publish the provider.
dotnet publish CredentialProvider.Microsoft/CredentialProvider.Microsoft.csproj  \
  -c Release  \
  -f net6.0   \
  -o "$pluginDir"

Yeah, the netcore plugin is expected to use dotnet CredentialProvider.Microsoft.dll, so seems like a Rider issue here? The default NuGet libraries will do the correct thing here, so guessing Rider is initializing or using the SDK in a non-standard way here. Are any of these environment variables set? https://learn.microsoft.com/en-us/nuget/reference/extensibility/nuget-cross-platform-plugins#plugin-installation-and-discovery

@JohnSchmeichel

Are any of these environment variables set?

no, I use default set-up for the sdk and dotnet cli, no additional path configuration

Yeah, the netcore plugin is expected to use dotnet CredentialProvider.Microsoft.dll, so seems like a Rider issue here?

I guess, it is a Rider issue, but can't say definitely, I don't know internals of the tool.

I have created the same issue in YouTrack: https://youtrack.jetbrains.com/issue/RIDER-96160/Credential-Manager-Rider-Linux

Have you tried changing this setting? On my machine it defaults to "Rider Integrated" and that caused all sorts problems with Azure feeds. Changing it to CLI allows me to work with Azure Nuget feeds without issues.

yes, I have changed it to the third option, and Rider threw the error from the description.
