Passwordless Managed Identity for ASP.NET Core on Azure — system vs user-assigned overview, EF Core + Azure SQL, BlobClient with DefaultAzureCredential, Key Vault RBAC, and local dual-mode config. Not a Blob upload UX rewrite.
Wire Azure Key Vault into ASP.NET Core configuration — AddAzureKeyVault, secret name mapping, reload/sentinel patterns, leak-prevention with Serilog, Key Vault references vs App Settings, and rotation habits. Pairs with Managed Identity; not a full App Service deploy rewrite.
Lessons from shipping ASP.NET Core APIs to Azure App Service in healthcare and SaaS — configuration, deployment slots, secrets, health checks, and the failures that only show up after go-live.
Use Azure Service Bus from ASP.NET Core — ServiceBusClient, processors in BackgroundService, queues vs topics vs sessions, JSON pitfalls, peek-lock, and where the transactional outbox fits. Not an outbox theory rewrite.
Run Azure Functions isolated worker for .NET beside an ASP.NET Core API — Program.cs DI, HTTP triggers, shared contracts, local Core Tools, and when Functions should not replace App Service.
