Some workloads in prod for four weeks, others been executing daily integration tests for a couple. So far no blockers, only had a couple new SDK analyzer warnings that broke builds as we treat warnings as errors, all minor fixes So can say with some experience,that it looks pretty good for November.

It's kinda cool that you can pipe C# directly into dotnet run since .NET 10, so you can easily use C# as an inline script. Here is a Cake.Sdk task handling AI:
#dotnet #csharp

$YAML C# - script: | set -euo pipefail cat <<'EOF' | dotnet run - #:sdk Cake.Sdk@6.3.0 #:package OpenAI@2.5.0 #:package xunit.v3.assert@4.0.2 using OpenAI; using OpenAI.Chat; using System.ClientModel; using Xunit; Task("Pong") .Does(async () => { var client = new ChatClient( model: Environment.GetEnvironmentVariable("LLAMA_CHAT_MODEL")!, credential: new ApiKeyCredential(Environment.GetEnvironmentVariable("OPENAI_API_KEY") ?? "local"), options: new OpenAIClientOptions { Endpoint = new Uri(Environment.GetEnvironmentVariable("LLAMA_BASE_URL")!) }); ChatCompletion completion = await client.CompleteChatAsync("Reply with exactly: pong"); string? text = completion.Content is [var content] ? content.Text?.Trim() : null; Information($"Response: {text}"); Assert.Contains("pong", text, StringComparison.OrdinalIgnoreCase); }); RunTarget("Pong"); EOF displayName: Test Cake.Sdk against local llama.cpp timeoutInMinutes: 10$

There’s something poetic about receiving an email from a company requesting permission to email you... ...because they lack my opt-in to get their emails.
