Unlocking the Power of DeepSeek with C# and .NET

Artificial Intelligence (AI) is transforming the way we build software, and DeepSeek is at the forefront of this revolution. As a C# or .NET developer, you now have the tools to seamlessly integrate cutting-edge AI capabilities into your applications. In this blog post, we’ll explore what DeepSeek is, how it can benefit developers, and how you can interact with it using C#.

How Can We Interact with It Using C#?

Thanks to Microsoft’s efforts, interacting with AI services like DeepSeek is incredibly straightforward. If you’re a C# developer, you can use the Microsoft.Extensions.AI.OpenAI library to interact with DeepSeek’s API. Here’s how you can get started:

Step 1: Create an API Key

To begin, you’ll need an API key from DeepSeek. Visit https://platform.deepseek.com/api_keys, create an account, and generate a new API key.

Step 2: Install the Required NuGet Package

Install the Microsoft.Extensions.AI.OpenAI package using the NuGet Package Manager or run the following command in the Package Manager Console:

Install-Package Microsoft.Extensions.AI.OpenAI

Step 3: Set Up the Chat Client

Once you’ve installed the package, you can create a chat client to interact with DeepSeek’s models. Here’s an example of how to set it up:

private IChatClient GetChatClient(string apiKey, string modelId)
{
    var client = new OpenAIClient(new ApiKeyCredential(apiKey), new OpenAIClientOptions()
    {
        Endpoint = new Uri("https://api.deepseek.com/v1"),
    });

    var builder = new ChatClientBuilder(client.AsChatClient(modelId));

    if (modelId != "deepseek-reasoner")
    {
        // The 'deepseek-reasoner' model does not support tool calling.
        builder.UseFunctionInvocation(null, (r) =>
        {
            // Set the maximum number of iterations per request to 1 to prevent infinite function calling.
            r.MaximumIterationsPerRequest = 1;
        });
    }

    return builder.Build();
}

Step 4: Call the DeepSeek API

With the chat client set up, you can now call the DeepSeek API to generate responses. Here’s an example:

var chatClient = GetChatClient("your-api-key", "deepseek-chat");

var prompts = new List<ChatMessage>
{
    new(ChatRole.User, "What is Orchard Core?"),
};

var result = await chatClient.CompleteAsync(prompts);

foreach (var choice in result.Choices)
{
    Console.WriteLine(choice.Text);
}

Supported Models

As of this blog post, DeepSeek supports two models:

• deepseek-chat: Ideal for conversational AI and natural language interactions.
• deepseek-reasoner: Designed for more complex reasoning tasks.
