Aspire secrets, AI agents, architecture choices
Multiline Aspire config, RAG in Agent Framework, GitHub Copilot SDK, SQL decomposition, code architecture, Native AOT testing, and API versioning updates.
Jasen's top three picks
- 1 Using multiline Parameters for Aspire and ASP.NET Core with user secrets and Azure default deployments
