Remarks

This method searches for embedded resources in the same assembly as the control.

If multiple images are available for type, this method retrieves the image that is closest to desiredSize. This method is not guaranteed to return an image that matches desiredSize exactly.

The object returned by this method can be set as the Content property of a ContentControl.

The default implementation of this method searches for images that are named Namespace.ControlName.Icon.Extension.

Currently, only the following extensions are recognized:

• .png

• .bmp

• .gif

• .jpg

• .jpeg
