# Guides: adding AI to your .NET applications

Reference pages rather than opinion pieces: what you need to know to add AI to an existing .NET and Microsoft estate, with the code, the decision tables and the sources. Every guide carries the date it was last revised.

- [Semantic Kernel or Microsoft Agent Framework: what to do with an existing .NET application](https://gilabs.fr/en/guides/semantic-kernel-agent-framework/) (updated on 2026-09-30): Agent Framework 1.0 shipped in April 2026 and Semantic Kernel has moved to maintenance. What changes in a .NET application, what stays put, the code before and after, and when to migrate.
- [RAG on SQL Server 2025: a reference architecture for an existing .NET application](https://gilabs.fr/en/guides/rag-sql-server-2025/) (updated on 2026-09-30): Wiring RAG into a .NET and SQL Server application without a separate vector store: the VECTOR type, chunking that follows the documents, permissions enforced in the query, an Agent Framework agent. Complete, tested code on GitHub.
