Like many programmers, I back up the software I am coding into a version control system. But this is not the problem I am having. Another coworker has gotten my source code and has tried to rebuild the project. And so here, I uncover an issue. I got some open source control from RadiantQ that I use in the project. It is referenced in one of my XAML files. But it seems to be hidden somewhre. Does anyone have any idea how to find this component?
