The following example shows a complete ActivityValidator used for a custom activity. The custom activity is a ConsoleWriteLineActivity activity that has a single dependency property named Msg of type String. The validator ensures that the Msg property is set. If it is not set, the compiler displays an error when the Validate(ValidationManager, Object) method is called on the ActivityValidator and the compilation fails.
