Reviewer's verdict

Skip this unless you're a .NET developer already using Semantic Kernel and just need the latest code snippet. It doesn't teach the 'why' behind function calling.

Decision summary

2.5/5 Last verified: August 31, 2026

Best for

Developers already in the Semantic Kernel ecosystem who need a quick syntax update.

Watch for

No conceptual explanation; it's a code-paste exercise.

Developers already in the Semantic Kernel ecosystem who need a quick syntax update.

Who should skip it

Beginners trying to understand what function calling is or how it works conceptually.

Pros

  • Provides a concrete code example for automatic function calling.
  • The sandbox environment works without local setup.
  • Completely free to access the material and code.

Cons

  • No conceptual explanation; it's a code-paste exercise.
  • Assumes deep familiarity with Semantic Kernel, making it inaccessible to newcomers.
  • The 'Suggest Concerts' exercise feels disconnected and doesn't build up to the main topic.

Staring at the `Program.cs` file in the sandbox, the instructions told me to copy-paste an entire block of code to enable automatic function invocation. I did. I ran it. It worked. And I learned absolutely nothing.

This isn't a course. It’s a documentation page disguised as a training module. There is zero explanation of the underlying mechanism. What is the `Kernel` doing? How does it parse the function signatures? How does it decide which function to call based on the prompt? The module doesn't care. It just shows you the new, simplified syntax in the latest Semantic Kernel SDK.

It’s for people who already know how all this works and just need the updated method call. For a student like me trying to piece together how these agentic systems are built, this was a waste of time. I spent 40 minutes clicking through, and the only thing I came away with is a code snippet I could have gotten from a GitHub repo's README. It’s free, yes, but my time isn’t. I ended up finding a YouTube video that actually drew diagrams and explained the request-tool-call-response loop, which was infinitely more useful.

If you're new to the concept of function calling, go find that video. Don't start here.
