Removes deprecated SharedTokenCache, Adds Azure Pipelines and Azure Developer CLI credentials

[Copilot]

Audits and consolidates the Azure.Identity credential types available in Get-AzToken, removing deprecated options and adding previously missing ones.

Changes Made

Removed

• Removed deprecated SharedTokenCache from the -CredentialPrecedence parameter and the default non-interactive credential chain (TokenManager.NonInteractive.cs), as SharedTokenCacheCredential is deprecated in Azure.Identity

Added

• Added AzureDeveloperCli to the -CredentialPrecedence parameter and the non-interactive credential chain, allowing use of Azure Developer CLI (azd) credentials
• Added -AzurePipelines parameter set to Get-AzToken for Azure Pipelines service connection OIDC authentication (AzurePipelinesCredential), backed by a new TokenManager.AzurePipelines.cs

Files Changed

• source/AzAuth.PS/Cmdlets/GetAzToken.cs — new -AzurePipelines parameter set, removed SharedTokenCache from -CredentialPrecedence
• source/AzAuth.Core/TokenManagerAuthMethods/TokenManager.NonInteractive.cs — replaced SharedTokenCacheCredential with AzureDeveloperCliCredential
• source/AzAuth.Core/TokenManagerAuthMethods/TokenManager.AzurePipelines.cs — new file implementing AzurePipelinesCredential auth
• tests/Get-AzToken.Tests.ps1 — added coverage for the -AzurePipelines parameter set
• docs/help/Get-AzToken.md — documented the new -AzurePipelines parameter set and removed SharedTokenCache from -CredentialPrecedence
• CHANGELOG.md — updated [Unreleased] section to reflect net changes

Original prompt

Can you go through the issues and match the various suggested new auth flows to currently available msal ones? Some existing ones in the module have been deprecated as well.

I'd like a consolidated list on which authentication methods / flows (such as managed identity, device code, interactive browser, client credentials etc) are available in MSAL, which ones I have as part of the PowerShell module, which ones I should add, as well as which ones I should remove.

For each one you find that I need to do something with, please create an issue or add to the existing ones, and branch off agents to implement each change.

@copilot Aren't there any other credential types that I'm missing from this namespace in Azure.Identity? https://learn.microsoft.com/en-us/dotnet/api/azure.identity?view=azure-dotnet

Yes, after auditing all exported TokenCredential types in Azure.Identity 1.19.0, four were missing. Implemented in commit 2a53743:

Added to NonInteractive chain:

• WorkloadIdentityCredential — reads from env vars (AZURE_FEDERATED_TOKEN_FILE, AZURE_CLIENT_ID, AZURE_TENANT_ID) set by Kubernetes workload identity. Now available as "WorkloadIdentity" in -CredentialPrecedence.

New explicit parameter sets:

• -AzurePipelines — AzurePipelinesCredential for Azure Pipelines OIDC service connection auth (requires -ServiceConnectionId + -SystemAccessToken)
• -OnBehalfOf — OnBehalfOfCredential for OAuth 2.0 on-behalf-of flow (3 variants: -ClientSecret, -ClientCertificate, -ClientCertificatePath), with -UserAssertion
• -AuthorizationCode — AuthorizationCodeCredential for OAuth 2.0 authorization code flow, with optional -RedirectUri

Excluded (intentionally):

• UsernamePasswordCredential — marked [Obsolete] in Azure.Identity 1.19.0 (doesn't support MFA)
• VisualStudioCodeCredential — already removed in issue Remove deprecated Visual Studio Code credential #145 (deprecated)
• DefaultAzureCredential / ChainedTokenCredential — used internally only

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• learn.microsoft.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot can you ensure that the docs changes actually reflect the changes we made in the commits (removing some stuff)

Verified — the docs are already in sync with the code. All 11 parameter sets in the C# match the 11 SYNTAX blocks in the docs, all 23 parameters match exactly, and there are no stale OnBehalfOf, AuthorizationCode, UserAssertion, or RedirectUri references anywhere in Get-AzToken.md.

@copilot Yeah but go through the changes you made in other files, changelog for example.

@copilot Yeah but go through the changes you made in other files, changelog for example.

Fixed in 6f20c1a. The changelog had stale Added entries for -OnBehalfOf and -AuthorizationCode that were introduced in one commit and then removed in the next — since those features were never in the original codebase and were never shipped, the entries were removed entirely. The [Unreleased] section now only reflects the net changes: adding AzureDeveloperCli/WorkloadIdentity to CredentialPrecedence, adding -AzurePipelines, and removing deprecated SharedTokenCache.

@copilot Can you update the description of the PR with the actual changes after all the iterations now?

Updated the PR description to reflect the actual net changes across all iterations:

• Remove deprecated SharedTokenCache from CredentialPrecedence and the non-interactive chain
• Add AzureDeveloperCli to CredentialPrecedence and the non-interactive chain
• Add -AzurePipelines parameter set (new TokenManager.AzurePipelines.cs)
• Corresponding updates to tests, docs, and changelog
