Hi! By day, I'm a .NET and open source enthusiast and a Microsoft Visual Studio and Development Technologies MVP. By night, I'm a husband and father. Somewhere in between the two I write stuff here.

Default Interface Members, What Are They Good For?

In my last post I promised to look at some of the use cases where I think it's worthwhile to consider using default interface members. They're certainly not going to replace many existing conventions, but I have found some situations where targetted use can lead to cleaner, more maintainable code (at least in my own opinion).


Default Interface Members and Inheritance

Default interface members (or "DIM" as I've seen the feature called) is a new language feature available in C# 8 that lets you define implementations directly in an interface. I started out with the intent of writing about use cases for the feature, but ended up writing so much that I decided to split the post in two. This part deals with how default interface members need to be invoked and the differences in semantics between class inheritance and default interface member implementation.


Some Thoughts On Feelings In Open Source

It's been a while since I've posted anything about open source communities, but that doesn't mean I haven't continued to think about them. It's an issue that's near and dear to me and I spend a lot of time considering different aspects of open source. I'd like to take a moment to talk about one of those in particular: feelings. More specifically, why they matter in open source and some ideas on how best to incorporate them into our open source interactions.
