Keeping the Compiler Happy: Null Member Variable Compile Errors in C#

Wait! This won't be boring! Yes, I know -- this probably isn't the most exciting topic ever, but I ran into some problems this week and I actually learned some cool stuff about nullability in C# and the compiler.

The issue I was running into was member variable initialization inside of a class. WAIT! Please don't quit on this article! I swear it gets better! I started off with a simple class, but it had complex initialization logic that involved multiple method calls and a bunch of calculations. Simple enough but I couldn't get it to compile because I kept getting nullability errors from the compiler.

Debugging Complex Classes with the [DebuggerDisplay] Attribute

Here's a scenario I ran into just last week. I was working on some code to edit PowerPoint PPTX files using C# and the OpenXML libraries. If you've ever tried using them before, you know that the OpenXML libraries are impossibly complex and nearly impossible to understand. And as much as I might have wanted to keep my code simple, I was losing and the complexity was growing.

Integration Testing in ASP.NET Core with WebApplicationFactory

Integration testing is a crucial step in ensuring that your application behaves correctly when different components interact with one another. In ASP.NET Core, the WebApplicationFactory<TEntryPoint> class makes it easier to test your web applications by allowing you to spin up an instance of your app in-memory and run integration tests against it.

Cross-Platform Readiness, Straight from the Experts

In today's diverse development landscape, cross-platform readiness isn't just a nice-to-have -- it's a necessity. Developers are increasingly tasked with ensuring their applications run smoothly across multiple operating systems and environments. Python and Blazor, both designed with cross-platform capabilities in mind, are indispensable tools in a modern developer's toolkit.

Building Applications with the Modern SQL Using AI and Microsoft Fabric

Devs surely do still love their SQL, but Microsoft executives are touting what they call "modern SQL" for building applications using the latest and greatest data technologies.

So what are those technologies that provide a new take on your beloved and familiar SQL? You start off with, of course, AI, specifically generative AI -- Copilots at Microsoft -- that has transformed software development along with the rest of IT. Then, being firmly in the Microsoft development camp, you add Microsoft Fabric, which is an end-to-end analytics/data platform that encompasses data movement, processing, ingestion, transformation, real-time event routing and report building.

Getting Started with GitHub Copilot Chat

Hey Y'all! VSLive @ Microsoft HQ is happening the first week of August. While I won't be there, my good friend Brian Randell will, and he has a couple of Copilot sessions you won't want to miss. One of the things I'm betting will come up in those sessions is GitHub Copilot Chat.

Monorepos: Are They a Good Thing?

In the world of software development, managing source code effectively is crucial for the success of projects, especially as they scale. One of the most important decisions teams must make is how to structure their codebase: using a monolithic repository (monorepo) or multiple repositories (multirepo).

This article explores the advantages and disadvantages of adopting a monorepo, with a focus on how platforms like GitHub and Azure DevOps support this model.

Getting a Grip on Dependency Injection

.NET supports the Dependency Injection (DI) software design pattern, which Microsoft describes as a technique for achieving Inversion of Control (IoC) between classes and their dependencies, such that components receive their dependencies from an external source (usually a framework or container), allowing the caller to provide necessary dependencies rather than the component creating them internally.

How To Harness AI from the Command Line

Back in January, I predicted this would be the year of AI. In February I gave you an introduction to GitHub Copilot. Now, with the general availability release of GitHub Copilot in the CLI, you can have all the power of AI and GitHub Copilot while never having to leave the safety of your command line.
