Persist AI Agent Memory in ASP.NET Core (Microsoft Agent Framework)

In this third video from my Microsoft Agent Framework series, I continue building a real AI-powered system in ASP.NET Core.

So far, our AI agents work, but they have one major limitation: they forget everything after restart. In this part, we are going to fix that by adding persistent storage and saving conversations in a database using Entity Framework and PostgreSQL.

By the end of this video, you will see:

• how to integrate Entity Framework with your AI agent system;
• how to design entities for conversation storage;
• how to serialize AI messages (including polymorphic content);
• how to implement a DB-based conversation store;
• how to handle LLM message ordering issues.

If you're building real AI systems in .NET - this series is for you.
