Take the following steps to start a project and to add some code that will demonstrate the automated annotation features of the LEADTOOLS Silverlight Control.

Build, and Run the program to test it.
Click the "Load" button and select a valid image.
NOTE: if you encounter and "Invalid File Format" or "Feature Not Supported" exception, please refer to the topic Invalid File Format/Feature Not Supported.
Use the toolbar above the viewer to select annotations. The radio buttons will allow you to switch between design and run mode.
