Semantic Kernel Connector to DashScope

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-v2"
  }
}

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);
    });
