error in dotnet quick start

[ruairica]

dotnet version
10.0.101

Sdk version:
<PackageReference Include="GitHub.Copilot.SDK" Version="0.1.12" />

Steps to reproduce:

• Create a console app with dotnet new console -n test
• cd test
• dotnet add package GitHub.Copilot.SDK
• Paste the quick start from the dotnet readme into Program.cs

using GitHub.Copilot.SDK;

// Create and start client
await using var client = new CopilotClient();
await client.StartAsync();

// Create a session
await using var session = await client.CreateSessionAsync(new SessionConfig
{
    Model = "gpt-5"
});

// Wait for response using session.idle event
var done = new TaskCompletionSource();

session.On(evt =>
{
    if (evt is AssistantMessageEvent msg)
    {
        Console.WriteLine(msg.Data.Content);
    }
    else if (evt is SessionIdleEvent)
    {
        done.SetResult();
    }
});

// Send a message and wait for completion
await session.SendAsync(new MessageOptions { Prompt = "What is 2+2?" });
await done.Task;

dotnet run
