Task-It Series This post is part of a series of blog posts and videos about the Task-It (task management) application that I have been building with Silverlight 4 and Telerik's RadControls for Silverlight 4. For a full index of these resources, please go here. One of the posts listed in the index provides a full source download for the application, and I will be referring to that source code in this post.

There are quite a few, and we will be adding more as we mature JustCode.    What Do All of Those Markers DO?

The new standalone WebUI Test Studio 2010 (its official launch was announced in my previous post) includes a couple of built from scratch modules which we’ll describe in this blog. I’ll start with the important features of the Test Lists in the QA Edition. Record and execute a single test Recording and execution of a single test case is pretty straight forward thanks to a cool hint on the startup screen:   With the QA edition you can quickly create a new project, add a test in the project and launch the recorder for your first test. You can ...
