Sourced from Azure.Identity's releases.

1.16.0

1.16.0 (2025-09-09)

Features Added

• Added a new DefaultAzureCredential constructor that accepts a custom environment variable name for credential configuration. This provides flexibility beyond the default AZURE_TOKEN_CREDENTIALS environment variable. The constructor accepts any environment variable name and uses the same credential selection logic as the existing AZURE_TOKEN_CREDENTIALS processing.
• Added DefaultAzureCredential.DefaultEnvironmentVariableName constant property that returns "AZURE_TOKEN_CREDENTIALS" for convenience when referencing the default environment variable name.
• AzureCliCredential, AzurePowerShellCredential, and AzureDeveloperCliCredential now throw an AuthenticationFailedException when the TokenRequestContext includes claims, as these credentials do not support claims challenges. The exception message includes guidance for handling such scenarios.
• When AZURE_TOKEN_CREDENTIALS or the equivalent custom environment variable is configured to ManagedIdentityCredential, the DefaultAzureCredential does not issue a probe request and performs retries with exponential backoff.

Bugs Fixed

• Fixed AzureDeveloperCliCredential hanging when the AZD_DEBUG environment variable is set by adding the --no-prompt flag to prevent interactive prompts (#​52005).
• BrokerCredential is now included in the chain when AZURE_TOKEN_CREDENTIALS is set to dev.
• Fixed an issue that prevented ManagedIdentityCredential from utilizing the token cache in Workload Identity Federation environments.
• Fixed a bug in DefaultAzureCredential that caused the credential chain to be constructed incorrectly when using AZURE_TOKEN_CREDENTIALS in combination with DefaultAzureCredentialOptions.

Other Changes

• The BrokerCredential is now always included in the DefaultAzureCredential chain. If the Azure.Identity.Broker package is not referenced, an exception will be thrown when GetToken is called, making its behavior consistent with the rest of the credentials in the chain.
• Updated Microsoft.Identity.Client dependency to version 4.76.0.
• Updated Microsoft.Identity.Client.Extensions.Msal dependency to version 4.76.0.

Breaking Changes

Behavioral Breaking Changes

• Deprecated SharedTokenCacheCredential. The supporting credential (SharedTokenCacheCredential) was a legacy mechanism for authenticating clients using credentials provided to Visual Studio. For brokered authentication, consider using InteractiveBrowserCredential instead. The following changes have been made:
  • SharedTokenCacheCredential class is marked as [Obsolete] and [EditorBrowsable(EditorBrowsableState.Never)]
  • SharedTokenCacheCredentialOptions class is marked as [Obsolete] and [EditorBrowsable(EditorBrowsableState.Never)]
  • DefaultAzureCredentialOptions.ExcludeSharedTokenCacheCredential property is marked as [Obsolete] and [EditorBrowsable(EditorBrowsableState.Never)]
  • SharedTokenCacheUsername property is marked as [Obsolete] and [EditorBrowsable(EditorBrowsableState.Never)]
  • SharedTokenCacheCredential is no longer included in the DefaultAzureCredential authentication flow

Bugs Fixed

• Tenant ID comparisons in credential options are now case-insensitive. This affects AdditionallyAllowedTenants values which will now be matched against tenant IDs without case sensitivity, making the authentication more resilient to case differences in tenant IDs returned from WWW-Authenticate challenges (#​51693).

Other Changes

• BrokerAuthenticationCredential has been renamed as BrokerCredential.

• Added the EditorBrowsable(Never) attribute to property VisualStudioCodeTenantId as TenantId is preferred. The VisualStudioCodeTenantId property exists only to provide backwards compatibility.
