    I'm trying to follow this tutorial:

    This is my source code:

    using Microsoft.Extensions.AI;
using Microsoft.Extensions.AI.Ollama;

namespace Chat
{
    internal class Program
    {
        static async Task Main(string[] args)
        {
            IChatClient chatClient =
                new OllamaChatClient(new Uri("http://localhost:11434/"), "phi3:mini");

            // Start the conversation with context for the AI model
            List<ChatMessage> chatHistory = new();

            while (true)
            {
                // Get user prompt and add to chat history
                Console.WriteLine("Your prompt:");
                var userPrompt = Console.ReadLine();
                chatHistory.Add(new ChatMessage(ChatRole.User, userPrompt));

                // Stream the AI response and add to chat history
                Console.WriteLine("AI Response:");
                var response = "";
                await foreach (var item in
                    chatClient.CompleteStreamingAsync(chatHistory))
                {
                    Console.Write(item.Text);
                    response += item.Text;
                }
                chatHistory.Add(new ChatMessage(ChatRole.Assistant, response));
                Console.WriteLine();
            }
        }
    }
}

    The problem is that I'm getting this error message:

    The type or namespace name 'Ollama' does not exist in the namespace 
'Microsoft.Extensions.AI' (are you missing an assembly reference?)

'IChatClient' does not contain a definition for 
'CompleteStreamingAsync' and no accessible extension method 
'CompleteStreamingAsync' accepting a first argument of type 
'IChatClient' could be found (are you missing a using directive or an assembly 
reference?)

    There have been some breaking changes since the tutorial was published.

    Here is a corrected version of the code, which works with the latest versions of the Github packages:

    using System.ComponentModel;
using Microsoft.Extensions.AI;

namespace Chat
{
    internal class Program
    {
        static async Task Main(string[] args)
        {
            IChatClient client = new ChatClientBuilder(new OllamaChatClient(new Uri("http://localhost:11434"), "phi4"))
                .UseFunctionInvocation()
                .Build();

            // Start the conversation with context for the AI model
            List<ChatMessage> chatHistory = new();

            while (true)
            {
                // Get user prompt and add to chat history
                Console.WriteLine("Your prompt:");
                var userPrompt = Console.ReadLine();
                chatHistory.Add(new ChatMessage(ChatRole.User, userPrompt));

                // Stream the AI response and add to chat history
                Console.WriteLine("AI Response:");
                var responseString = "";
                var response = client.GetStreamingResponseAsync(chatHistory);
                await foreach (var update in response)
                {
                    Console.Write(update);
                    responseString += update;
                }
                chatHistory.Add(new ChatMessage(ChatRole.Assistant, responseString));
                Console.WriteLine();
            }
        }
    }
}
