Since I started using RX, events have played less and less of a role in my code. It’s true that in the same way LINQ has relegated for-loops to only niche situations, RX is making events all but obsolete. What does this mean for the
EventAggregator? Certainly, you can implement your own version using RX. But, if you happen to be using MEF (preferably as your IOC container) you can even get rid of that. Continue reading “Patterns with MEF and RX”
Perhaps one of the most ambivalent things about putting code on GitHub is that it’s more or less an open project. It’s great that people (including yourself) can continue to work on it, but it seems to lack closure so that you can move on with your life.
So one of the things that I’ve been missing in my
BindableBase class is property coercion, a la dependency properties. It’s a pretty smart idea; you can keep values in a valid state without pushing change notification. Unfortunately, there are some problems that crop up pretty quickly in
INotifyPropertyChanged based view models. Continue reading “Coercing ViewModel Values with INotifyPropertyChanged”
It’s sad how much controversy there is in doing something as simple as raising property change notification to our subscribers. It seems to me that we should have settled on something by now and moved on to bigger problems, yet, still, I see developers at every level of experience doing it differently.
I want to inform you all that you’re doing it wrong. Continue reading “The Right Way to do INotifyPropertyChanged”
When I first started working with WPF professionally, it wasn’t very long before I realized I needed to change the system theme of WPF to give my users a consistent experience across platforms. Not to mention that Vista’s theme was much improved over XP and even more so over the classic theme. Conceptually, this should be feasible, since WPF has its own rendering engine, as opposed to WinForms relying on GDI. Continue reading “How to Actually Change the System Theme in WPF”
Last week I interviewed colleague Kalani Thielen, Lab49’s resident expert on programming language theory. We discussed some of the new languages we’ve seen this decade, the recent functional additions to imperative languages, and the role DSLs will play in the future. Read on for the full interview.
