It’s probably one of the most interesting moments to do a post mortem for a Silverlight project. The entire Microsoft ecosystem is boiling around the Silverlight OR HTML 5 debate fueled by the recent PDC and some statements from Microsoft officials. The interesting part about it is that it is a false debate, and like most false debates it will probably lead to nowhere. The simple truth is that Microsoft’s commitment to Silverlight has not changed a bit, and Silverlight i...See More

I have a client that has a few Windows Services and some EXEs that run on a computer to perform various business functions. Every once in a while, the processes fail and need to be restarted. I helped the client write a Windows Service to monitor their running processes and ensure that they are up and running and to notify them and to attempt to restart those processes. As part of this process, I had to write a class to get a list of all of the processes running on the c...See More

If you are a .NET software developer, you have heard of F#. You may have read an article, seen a talk at a user group, or otherwise heard the buzz. However, if those means of reaching you have failed, at the very least, you have noticed it conspicuously appear in the list of languages you can base a solution on in Visual Studio 2010. If you write code on the .NET Framework, you would have to be living under a rock to have not heard of F#.

Since the beginning of .NET, developers have been able to take advantage of multithreading when developing applications. In fact we’ve been given more than one programming model to accommodate just about any requirement that might come across. There’s the Thread class, the Thread Pool, the Async Pattern, and the Background Worker. Well, as if that isn’t enough, we now have a couple of more patterns that bring with them another genre - parallel programming.

ListBoxes suck. Except that statement is not true anymore. Not in WPF and Silverlight anyway, where ListBoxes have evolved from simplistic controls to true workhorse objects. ListBoxes have been around since the beginning of Windows (and other GUIs) and have served a pervasive yet simple purpose, which can be summed up as “show me a list of labels in a list with a scroll bar.” A premise that has its uses but is not sophisticated enough for advanced data presentation, ...See More
