How to Migrate Your .NET 8 and 9 Apps to .NET 10 with Visual Studio and GitHub Copilot

.NET 8 and 9 are both driving toward the same cliff: end of support on 10 November 2026, at which point you stop getting security fixes and patches from Microsoft. The good news is that the upgrade to .NET 10 is usually a simple version bump, and Visual Studio’s GitHub Copilot modernization tooling can do most of the boring work for you regarding the NuGet package version upgrades. Why .NET 10 is the new baseline .NET 10 is the latest… Read More »How to Migrate Your .NET 8 and 9 Apps to .NET 10 with Visual Studio and GitHub Copilot

MQNet: Shipping a Rust Library to .NET via NuGet

I recently built MQNet .NET wrapper for mq, a jq-like query tool for Markdown. The project turned out to be a good exercise for several things at once: P/Invoke interop with a Rust library, cross-platform native compilation in GitHub Actions, and distributing native binaries through NuGet. In this blog post I will breakdown each of these topics.

What is mq?

mq is a Rust tool that lets you …

NuGet Package Restore Speed Improvement with Windows Dev Drive

I was listening to Jeffrey Palermo’s AI DevOps Podcast and in one episode Chet Husk mentioned that one practical way to improve .NET build performance is to use Windows Dev Drive for development-heavy file operations. That immediately sounded interesting, especially because NuGet restore is kind of workload that does a lot of file system activity.

So I decided to test one small change: move the global NuGet package cache to …

A first look at C# unions in .NET 11

C# is getting union types, and I wanted to try them out as soon as possible. In this post, I’ll show how to get them working with the current .NET preview SDK, what the setup looks like, and why unions can be a better fit than inheritance or interfaces in some cases.

To try out unions, you need the preview version of the .NET 11 SDK. You can install it …

Botello: Get Your Build Logs Out of CI/CD and Into the Hands of AI

Build logs are one of the most underutilized data sources in software development. Every time your CI/CD pipeline runs, it generates a wealth of information about your build process: compilation times, warnings, errors, project dependencies and target execution order. Yet in most organizations, these logs just sit there in the pipeline run history, only viewed when something breaks.

During last week, I built Botello to change that. Botello stands …

Azure Container App Jobs: A Simpler Approach to Background Tasks in Azure

Azure Container Apps Jobs is a feature that doesn’t get enough attention. While everyone defaults to Azure Functions, I’ve found that Container Apps Jobs is often the easier and more pragmatic way to run scheduled tasks or process Azure Service Bus events.

The Problem with Azure Functions

If you have used Azure Functions for scheduled jobs or batch processing, you know that setting is a bit pain the ass. First, …
