For some reason one of my favorite .NET Framework Class is the ErrorProvider class. This class allows you to visually indicate to the user that there is an error with one of the form controls. For example, if you have a user input form that allows the user to input information into a TextBox and the user tries to proceed without filling in the TextBox you can set the ErrorProvider to display an error icon, with an error hint, adjacent to the TextBox. The option of setting the BlinkStyle and BlinkRate is also neat.

It is pretty basic and simple to use, but for some reason I am fascinated by it.
