AboutInfo is a singleton. Use the AboutInfo.Instance property, to access the object. The following properties of this object represent the “About” information on the current application: AboutInfo.Company, AboutInfo.Copyright, AboutInfo.Description, AboutInfo.ProductName and AboutInfo.Version. The AboutInfo.AboutInfoString property is supposed to provide a summary information, concatenating the values of the other properties. In addition, there is the AboutInfo.LogoImageName property, that can be used to present the logo of the company that built the application.

The AboutInfo object is used internally to display the “About” informational block in the Windows Forms and ASP.NET Web Forms applications.

The following image demonstrates the About Action with the invoked informational pop-up window.
