Build, use, and share your own Design Libraries from within Visual Studio. Designbox is a new kind of Visual Studio Toolbox that lets you develop and reuse sets of properties and values called Designs. These control designs can be dragged and dropped directly into your WinForms applications to develop applications more quickly than ever. Designbox also contains a Design Gallery which lets you browse through and apply dozens of pre-defined designs to your WinForms controls with just a single click.
