WPF Toolbox Empty
问题 I am adding on to an existing WPF Project, and am running into an odd error. My Toolbox is empty. I am developing in a Windows 7 environment using Visual Studios 2008 run as Administrator. I have created a project from scratch, and the tools were there. However, when I load the existing project, there are no tools in the Toolbox. I do have an element in the UI selected. I fixed this once by going into Tools -> Choose Toolbox Items... -> WPF Components. I then added the tools that I needed.
