.NET: How to run Ollama Sample?

[ddobric]

Trying to compile the following sample:

https://learn.microsoft.com/en-us/agent-framework/agents/providers/ollama?tabs=ollama-native&pivots=programming-language-csharp

using System;
using Microsoft.Agents.AI;
using Microsoft.Extensions.AI;

// Create an Ollama agent using Microsoft.Extensions.AI.Ollama
// Requires: dotnet add package Microsoft.Extensions.AI.Ollama --prerelease
var chatClient = new OllamaChatClient(
    new Uri("http://localhost:11434"),
    modelId: "llama3.2");

AIAgent agent = chatClient.AsAIAgent(
    instructions: "You are a helpful assistant running locally via Ollama.");

Console.WriteLine(await agent.RunAsync("What is the largest city in France?"));

Unfortunately, it is not clear which nuget package should be used for type OllamaChatClient?

Also, following the project file references, it is not clear where this type comes from.

  <ItemGroup>
    <PackageReference Include="OllamaSharp" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\..\..\..\src\Microsoft.Agents.AI\Microsoft.Agents.AI.csproj" />
  </ItemGroup>

I guess it is some sync issue between the documentation of published packages.

After adding the package Microsoft.Extensions.AI.Ollama and slightly changing the code, the sample compiles.

@ddobric The type OllamaChatClient is part of the deprecated package Microsoft.Extensions.AI.Ollama. The current recommended approach is to replace the Microsoft.Extensions.AI.Ollama package with OllamaSharp and use the OllamaApiClient type.
