Mario · January 2019

Hi

Cheers,

... I just created an account here to ask exactly the same question :-)

I've just tried it and it works for me. I created a PAT according to these instructions:

https://docs.microsoft.com/en-au/azure/devops/organizations/accounts/use-personal-access-tokens-to-authenticate?view=vsts

From LINQPad's NuGet package manager, I went to settings, and entered the PAT into the password field. The username can be anything, such as ID.

yeah PAT works. I can swear this is what i did before posting this question, must have been some other issue:/

A customer of mine just ran into this problem as well for a feed service I run. It looks like the settings in the %AppData%/Nuget/Nuget.config file where overriding the values entered in the LinqPad UI. The URLs had to be an exact match and "Use legacy search" was enabled.

Hi there. I was having this exact same problem. An SO from 2017 led me in the right direction. https://stackoverflow.com/questions/40514300/how-to-use-visual-studio-team-services-as-a-nuget-feed-in-linqpad

It seems like linqPad refuses to authenticate with the V3 URIs.
I've tried:
https://mycompany.pkgs.visualstudio.com/_packaging/Feed/nuget/v3/index.json
https://mycompany.pkgs.visualstudio.com/_packaging/Feed/nuget/v3
With "Use Legacy Search Engine (Nuget V2)" checked and unchecked.

Everything works with this URI:
https://mycompany.pkgs.visualstudio.com/_packaging/Feed/nuget/v2
and "Use Legacy Search Engine (Nuget V2)" checked.

It would be nice if LinqPad just worked with the V3 URIs. Perhaps I'm doing something wrong too?

I can't reproduce this error with the V3 feed. However, after combing through the code, I've picked up a bug whereby the NuGet credentials can potentially be overridden by machine settings. Can you try the latest beta and let me know whether it makes any difference:

It started working for me when I switched to the new Azure urls starting with https://pkgs.dev.azure.com

Not sure why or if that was actually what made the difference for me but after changing from https://xyz.pkgs.visualstudio.com to https://pkgs.dev.azure.com it started working.

Hope this works for someone else too.

I couldn't connect to Azure Devops Artifacts.
I did the following:

Added PAT as per instructions above
Put the PAT as password
Used the BETA

That worked for me - i couldn't access it any other way.

Hi,

I still experience the problem with Linqpad 6.5.5. It throws me an exception Unauthorized.
I tried with several combinations it with the PAT, user name and password and none worked.

Does anybody experience the same issue?

I have recently switched to LinqPad 6 (6.7.5 x64) and I'm experiencing this issue. We have an on-prem Azure DevOps instance. I've created a PAT with all scopes. I created a nuget feed in LinqPad and left the username blank and the password is the PAT token. I keep getting the authentication 401 error.

FYI, I tested this and without changing the feed at all the feed works in LinqPad 5 but not 6. I get the 401 error in LinqPad 6.

JoeAlbahari · May 6

Have you re-started LINQPad after changing the username/password? (This is required by the NuGet API)

Kenni · May 27

Hi,
I can confirm that using PAT in LinqPad 6 (v6.8.3) doesn't work , but the exact same configuration works in LinqPad 5 (v5.41.00). I have tried different configurations (v2, v3, PAT with and without username etc.), but no luck - still gets a 401. I hope this gets fixed soon, as I would like to use C# 8 features.

JoeAlbahari · May 28

I still can't reproduce this error. My devops feed URI looks like this:

https://linqpad.pkgs.visualstudio.com/_packaging/doLINQPad/nuget/v3/index.json

The username box contains 'ID', although it seems anything can go here (as long as it's not blank).

The password box contains the PAT.

Note that you must restart LINQPad after editing the credentials - this is because the NuGet client library caches the credentials after they're first sent and there appears to be no way to clear that cache.

Had 401 error on v6.8.3 until I followed Joe's notes. 1. Ensure Id field has something in it, password is PAT. 2. Save. 3. Restart linqpad. All good!
