As I mentioned before, I have created a CodePlex project to track the development of a WPF PowerShell host using AvalonDock and AvalonEdit. It’s still in the very beginning stages, but it’s comparable to the code I used in this tutorial series (except that it’s using different technologies, all of which I’m new to). PowerShellWorkBench …

The reason for this is simple. PowerShell cmdlets (and …

In the last post, I discussed some of the reasons why you might want to write your own PowerShell hosting app. I realized later that I didn’t define what that meant. In general, there are 2 ways to include PowerShell technology in an application. Use the PowerShell objects (in the System.Management.Automation.* namespaces) to execute scripts, …

I’ve mentioned before that I use a homegrown PowerShell host in my work. I have been more than pleasantly surprised at how easy and how rewarding this is. In the last few weeks, I’ve seen a few articles that have gotten me thinking about writing a series of blog posts about how to get started. …
