Requirements: Use large models to obtain real-time information, such as current time, today's weather, check express delivery, etc., or use large models to analyze business data, you need to use the Function Calling function. Many articles on the Internet about Function Calling are very vague and do not explain clearly, and I understand this function based on the request information.
Let's take a look at the renderings first and use the large modelGet the current time, the weather in Shanghai, and the calculator that helped me turn on my computer, as shown in the figure below:

Function Calling
Large models may not be effective when facing real-time problems, mathematical calculations and other problems. You can use the Function Calling function to enable large models to interact with the outside world by introducing external tools.
Function Calling is a new function that connects large models with external tools and APIs to help large models move towards actual industrial implementation. Function Calling allows developers to obtain structured data from models more reliably without the need for users to input complex prompts.
When used, you can describe the functions and definitions of a set of functions to the model in natural language; During the conversation, when the large model feels that it needs to use a function, it will intelligently select the function and return to call the required parameters to meet the specific needs of the user. In other cases, the large model will not return a function and will continue the conversation. The large model does not directly call the function, but returns its corresponding input parameters, and you can call the function/API interface yourself.
In simple terms, Function Calling is a "translator" between natural language and information interfaces
Translate the natural language into the required functions and parameters, and return it to the large model caller
After the large model caller executes the function, the result is returned to the large model, and the large model can be summarized into natural language or continue to plan subtasks
The workflow diagram is shown below:
Semantic Kernel
The Semantic Kernel is a lightweight, open-source development kit that can be used to easily generate AI agents and integrate the latest AI models into C#, Python, or Java codebases. It acts as an efficient middleware, enabling rapid delivery of enterprise-level solutions.

C# calls Alibaba Cloud Tongyi Qianwen to execute Function Calling
Create a new .NET 8 console project with the following references:
The code is as follows:
Run the program, which is the rendering at the beginning, get the current time and Shanghai weather, and open the calculator.
