TestAPI Released!

User Settings in WPF

It’s been a while since my last post, so I figured I’d write something I just recently had to work on: user settings. In many client applications, you quickly run into the need to store application or user settings. There are a few options on how to do that, some of which are more complex…

One of the questions we frequently get when meeting with customers is whether or not to adopt WPF over WinForms, Win32 or some other technology. As much as I’d love to have the answer always be “of course!”, the reality is that it depends on a number of factors that need to be taken in…
