VisualStyler allows you to import new visual styles at design-time, visual styles can be imported directly from an
msstyles file or from a zip archive. The import visual style task can be found on the VisualStyle
designer and at the bottom of the VisualStyler
properties window. By default visual styles are automatically embedded into your application as a resource, unless the
SaveAsResource property is false.
Step 1. For this example we will use the component designer, Open the main form of your application and click on the VisualStyler component and select the designer tasks by clicking on the small arrow on the top right hand corner. This will reveal the designer panel as shown below, now click on the 'Import Visual Styles' link. 
Step 2. This will display the import style dialog. The default option is to import directly from an msstyles file, click Import to choose a msstyles file. 
Step 3. Select the msstyles file using the file open dialog, click Ok or Cancel.
Step 4. After selecting the file you will then see a preview of the visual style with the default color scheme. You can preview all of the available color schemes using the color scheme drop-down box. Click OK to accept the current selection or Cancel to quit. 
The style will now be converted to a VisualStyler file (.vssf) and saved in the skin gallery under 'Custom Skins'. If you are using the VisualStyler add-in, the skin will automatically be applied to any open forms, otherwise if the 'Save as Resource' option is set then the skin will be embedded in your application as a resource.

Important Notes
Don't be surprised if some visual styles only have one available color scheme or selecting other color schemes does not appear to change the skin, this is because these color schemes may only affect UI elements that you wouldn’t normally see in a winforms application such as the Taskbar, Explorer bar ect.
