SemanticKernel.DashScope

Make DashScope work with Semantic Kernel and Kernel Memory.

Get started with SemanticKernel

Add the NuGet package to your project.

dotnet add package Cnblogs.SemanticKernel.Connectors.DashScope

using Microsoft.SemanticKernel;

var builder = Kernel.CreateBuilder();
builder.Services.AddDashScopeChatCompletion("your-api-key", "qwen-max");
var kernel = builder.Build();

var prompt = "<message role=\"user\">Tell me about the Cnblogs</message>";
var response = await kernel.InvokePromptAsync(prompt);
Console.WriteLine(response);

ASP.NET Core with KernelMemory support

Install Nuget package Cnblogs.KernelMemory.AI.DashScope

Install Nuget package Microsoft.KernelMemory.Core

Install Nuget package Microsoft.KernelMemory.SemanticKernelPlugin

appsettings.json

{
  "dashScope": {
    "apiKey": "your-key",
    "chatCompletionModelId": "qwen-max",
    "textEmbeddingModelId": "text-embedding-v3"
  }
}

Program.cs

// Kernel Memory stuff
var memory = new KernelMemoryBuilder(builder.Services).WithDashScope(builder.Configuration).Build();
builder.Services.AddSingleton(memory);

// SK stuff
builder.Services.AddDashScopeChatCompletion(builder.Configuration);
builder.Services.AddSingleton(
    sp =>
    {
        var plugins = new KernelPluginCollection();
        plugins.AddFromObject(
            new MemoryPlugin(sp.GetRequiredService<IKernelMemory>(), waitForIngestionToComplete: true),
            "memory");
        return new Kernel(sp, plugins);
    });

Services

public class YourService(Kernel kernel, IKernelMemory memory)
{
    public async Task<string> GetCompletionAsync(string prompt)
    {
        var chatResult = await kernel.InvokePromptAsync(prompt);
        return chatResult.ToString();
    }

    public async Task ImportDocumentAsync(string filePath, string documentId)
    {
        await memory.ImportDocumentAsync(filePath, documentId);
    }

    public async Task<string> AskMemoryAsync(string question)

        // you can bundle created functions into a singleton service to reuse them

        return result.ToString();
