Learn how to build AI agents in C# with Semantic Kernel. Step-by-step .NET tutorial with runnable code, plugins, tool calling and best practices. Start building today. Building AI agents in C# used to mean gluing together HTTP calls, JSON schemas and a lot of hopeful string parsing. That era is over. With Microsoft Semantic Kernel , .NET developers now have a first-class agent framework that handles tool calling, memory, planning and multi-agent collaboration — all with strongly typed C# code, dependency injection and the async patterns you already know.
