OpenAI .NET 👾

The OpenAI .NET library provides convenient access to the OpenAI REST API from .NET applications. ✔️

The full API of this library can be found in the api.md file, and there are many code examples to help. For instance, the following snippet illustrates the basic use of the chat completions API:

ChatClient client = new(model: "gpt-4o", "OPENAI_API_KEY");

ChatCompletion completion = client.CompleteChat("Say 'this is a test.'");

Console.WriteLine($"[ASSISTANT]: {completion}");

The library is organized into several namespaces corresponding to OpenAI feature areas. Each namespace contains a corresponding client class:

• AssistantClient
• AudioClient
• BatchClient
• ChatClient
• EmbeddingClient
• FineTuningClient
• FileClient
• ImageClient
• ModelClient
• ModerationClient
• VectorStoreClient

Designing APIs for humans: Object IDs 🧑🏻‍💻

Ever wondered why Stripe uses foloowing format to generate unique IDs? Let’s dive in and break down how and why Stripe IDs are structured the way they are:

pi_3LKQhvGUcADgqoEM3bh6pslE
└┘└────────────┘
└─ Prefix └─ Randomly generated characters


You might have noticed that all Stripe Objects have a prefix at the beginning of the ID. The reason for this is quite simple: adding a prefix makes the ID human readable. ✔️

Without knowing anything else about the ID we can immediately confirm that we’re talking about a PaymentIntent object here, thanks to the pi_ prefix. This helps Stripe employees internally just as much as it helps developers integrating with Stripe.

$pi = $stripe->paymentIntents->retrieve(
  $id,
  [],
  ['stripe_account' => 'cus_1KrJdMGUcADgqoEM']
);

The above snippet is trying to retrieve a PaymentIntent from a connected account, however without even looking at the code you can immediately spot the error: a Customer ID (cus_) is being used instead of an Account ID (acct_). 🔖

Without prefixes this would be much harder to debug; if Stripe used UUIDs instead then we’d have to look up the ID to find out what kind of object it is and if it’s even valid. 👨‍💻

C# 14 - Extension Members 🚀

C# 14 adds new syntax to define extension members. The new syntax enables you to declare extension properties in addition to extension methods. ✔️

You can also declare extension members that extend the type, rather than an instance of the type. In other words, these new extension members can appear as static members of the type you extend.

The following code example shows an example of the different kinds of extension members you can declare:

public static class Enumerable
{
    // Extension block
    extension<TSource>(IEnumerable<TSource> source) // extension members for IEnumerable<TSource>
    {
        // Extension property:
        public bool IsEmpty => !source.Any();
        // Extension indexer:
        public TSource this[int index] => source.Skip(index).First();

        // Extension method:
        public IEnumerable<TSource> Where(Func<TSource, bool> predicate) { ... }
    }

    // extension block, with a receiver type only
    extension<TSource>(IEnumerable<TSource>) // static extension members for IEnumerable<Source>
    {
        // static extension method:
        public static IEnumerable<TSource> Combine(IEnumerable<TSource> first, IEnumerable<TSource> second) { ... }

        // static extension property:
        public static IEnumerable<TSource> Identity => yield return default;
    }
}

The members in the first extension block are called as though they're instance members of IEnumerable<TSource>, for example sequence.IsEmpty. The members in the second extension block are called as though they're static members of IEnumerable<TSource>, for example IEnumerable<int>.Identity.

The Hidden Cost of DateTime.Now in .NET 🕰

You're Using DateTime.Now — and It's Breaking Your Code … ❌

Let's be honest: We've all written this:

if (DateTime.Now > token.Expiry)
{
    return Unauthorized();
}

It works… until it doesn't.

In production, this little line can wreck your logic due to clock drift, time zone shifts, or mocking nightmares. 🐞

GitHub MCP Registry: The fastest way to discover MCP Servers 🔝

If you’ve tried connecting AI agents to your development tools, you know the pain: MCP servers scattered across numerous registries, random repos, buried in community threads — making discovery slow and full of friction without a central place to go. Meanwhile, MCP server creators are worn out from publishing to multiple places and answering the same setup questions again and again.

The GitHub MCP Registry launches as your new home base for discovering MCP servers. Whether you’re building with GitHub Copilot, agents, or any AI tool that speaks MCP, this is the place to find what you need. With GitHub already home to most MCP servers, the MCP Registry makes them dramatically easier to discover, explore, and use — helping developers find the right tools faster and contribute to a more open, interoperable ecosystem. ✔️

Preparing for the .NET 10 GC 🔥

In .NET 9 DATAS (Dynamic Adaptation To Application Sizes) got enabled by default, but .NET 9 is not an LTS release, so for many people they will be getting DATAS for the first time when they upgrade to .NET 10.


What does “application size” mean exactly?
This is the LDS (Live Data Size) from GC’s point of view, meaning that if we did the most aggressive GC possible, this is how much memory your application uses. Another way to look at it is this is your long lived data + whatever inflight data you have when a GC occurs.

The goal for DATAS is that you no longer need to do various configurations to try to achieve a heap size proportional to your application usage. The 2 main cases we target with DATAS are:

1) Bursty workloads running in memory constraint environments. DATAS aims to retract the heap size back when the application doesn’t require as much memory and grow it when the app requires more. This is especially important for apps running in containers with memory limits.

2) Small workloads using Server GC — for example, if someone wants to try out a small asp.net core app to see what the experience is like in .NET, DATAS aims provide a heap size much more inline with what the small app actually needs.
