Logging into C# Dev Kit causes 401 with individual license

[kroppt]

Type: Bug

1. Install C# Dev Kit
2. Open a solution with C# Dev Kit running
3. Log into C# Dev Kit with an individual license
4. See error logged under "C# Dev Kit": IdeBenefitsSource: Failed to fetch entitlements. Error: 'Error: Request to https://api.subscriptions.visualstudio.microsoft.com/Me/Entitlements/IDEBenefits?api-version=2023-03-26&caller=vscode failed with status code: 401 and response ""'
5. The language server does not function

The following did not help:

• Ungrant and regrant account access to C# Dev Kit
• Sign out and sign back in
• Double check I can sign in on visualstudio.microsoft.com
• Uninstall C# Dev Kit and C# extensions and re-install them

Thank you for the suggestion. Yes, I worked with only the C# extension, which does not need login. I disabled C# Dev Kit until this problem is fixed.

I'm also having this problem but on Ubuntu only. In my windows 11 setup it works fine but in the Ubuntu this error occurs.

@AndreyTretyak would you please take a look? Related is https://github.com/microsoft/vscode-dotnettools/issues/1384

I just tested this with the latest VSCode 1.95.0, C# 2.50.27, and C# Dev Kit 1.11.14.

The error shows up in the C# Dev Kit logs, but the behavior is a bit different. The LSP functionality appears to be working, but it's not clear whether the C# extension is falling back to Omnisharp or sticking with C# Dev Kit (somehow). It seems like it's working with the C# Dev Kit LSP.

If it helps, I noticed the Microsoft Authentication logs show the following:

Even though things are currently "working", I'd rather keep this open until we know it's fixed.
