azure-identity-dotnet

Azure Identity is the authentication library for .NET Azure SDK clients. It handles credential acquisition against Microsoft Entra ID, supporting managed identities, service principals, developer tools, and interactive flows through a unified API. DefaultAzureCredential automatically tries multiple auth methods in sequence, so the same code works in local dev and production. Instead of manually implementing OAuth token flows or managing credential refresh, the library handles token caching, retry, and environment detection automatically across every Azure SDK client.
