Welcome back, tech enthusiasts! 👋

After a couple of quieter weeks, this edition brings a well-rounded batch of updates. GitHub is rolling out sub-issues and new runner images, and there’s some much-needed clarity around MCP.

On top of that, there are solid reads on real-world Rust adoption, big performance gains in NuGet, and the evolving sustainability of open source libraries like AutoMapper and MediatR.

Here’s what’s inside this week:

• 🧩 GitHub sub-issues & new OS runner images

• 🧠 What MCP is (and why it matters)

• ⚙️ Datadog’s Rust rewrite for better performance

• 🚀 NuGet restore gets a 16x speed boost in .NET 9

• 💸 AutoMapper & MediatR move to commercial licensing

• 💾 Deep dive into Azure File Storage & access tiers

• 🧵 .NET 10 Preview 3, VB history, and Jon Skeet on records

Let’s dive in and explore the latest across the GitHub, Azure, and .NET landscape! New here? Subscribe here to stay updated.

GitHub Digest

From a simple issue with a title and description to nested issues like we know from Azure DevOps; issue management is coming a long way and went through some needed improvements. Learn more how GitHub build this sub-issue system:

Yup, the latest OS versions are available for selection as an agent to run your GitHub tasks on. They will become the official latest later this year.

As the title already suggests; what is that MCP and why is GitHub doing something with it:

Coding Corner

I know nothing about Rust, but it is interesting to read how it is possible to write even more optimized code by using a language like Rust. The Datadog team did not know Rust either, but found a couple of arguments to use this language for their telemetry delivering code. Read how their experience went and the gains they got.

You are most likely using NuGet restore daily; getting all the packages that your code depends on. The faster it works, the better. Not only does it keep you sane during development work, it also helps to keep the compute minute down in CICD scenarios, thus saving cost.

So there is a lot to gain to make this process faster, and it looks like that with dotnet 9 they were able to give it a 16 times speed boost:

After FluentValidations and MassTransit, the popular frameworks AutoMapper and Mediatr will also go commercial. Although an understandable move, it also shows that being successful with Open Source is hard.

Azure Updates & Insights

A lot of details about Azure File Storage. What is it, how to use it and what is the most cost effective way to run it:

.NET Nook

Want to play with the next version of dotnet? Preview 3 is available to try out.

GW Basic, Basica and Visual Basic; it was my first start with programming languages long long time ago. And Visual Basis is not dead yet, it is still a supported language and although it wont get any new features, you can still use it.

Read more about the history of the langauge that started many developers:

Jon Skeet knows a thing about computers; so when he writes about his experience with Records, it is worth a read:
