.NET Annotated Monthly | March 2023

Did you know? There is a difference between the terms “argument” and “parameter”, despite everyone using them interchangeably. As is explained in this Stack Overflow question: “A parameter is a variable in a method definition. When a method is called, the arguments are the data you pass into the method’s parameters.” Now you know what you can have an argument about with fellow developers!

We’d like to thank Stefan Pölz for curating this month’s featured content! He is an international speaker, JetBrains Community Contributor (.NET), Microsoft MVP (Developer Technologies) and co-organizer of meetups. Stefan tweets as 0x_F0, open sources on GitHub, and codes live on Twitch and YouTube.

Thank you JetBrains for granting me the opportunity to share my current passion: the .NET Compiler Platform. Well, passion is perhaps a bit of an understatement. For me it’s more of a hammer. And I try to make every problem I have look like a nail. Over the last two years I’ve talked a lot about Roslyn in general and Generators in particular, for example at the JetBrains .NET Days Online 2022.

Why am I so excited about Roslyn? Published as NuGet packages, the SDK exposes the Compiler APIs for both C# and Visual Basic. With these at our fingertips, we can write custom extension components, such as Diagnostic Analyzers (report warnings, errors, etc.) and Code Fixers (Alt+Enter code actions), by inspecting the syntax trees and semantic symbols. Additionally, there are the Workspace APIs (handle solutions, projects and documents) that I’m about to explore in my live stream in order to build a standalone .NET tool that facilitates common coding tasks. The Roslyn programming model does take some practice to get used to, but if it has taught me one thing, it’s to use the terms ”parameter” and ”argument” correctly 😉. This deeper understanding of the language carries over to my day job development, where I now more consciously use the latest syntactic sugar and compiler magic.

Certainly not everyone needs to become a compiler engineer. However I still want to encourage you to take a brief peek behind the scenes from time to time. I’m sure it will pay off for you too, one way or another. If you would like to know more about Roslyn, I leave you with some resources and tools to kick-start your journey:

May Roslyn be with you.
