.NET Components are third-party reusable components which have been created using the Microsoft .NET Framework. .NET Components may be components or controls that you have created yourself, purchased from a third-party, or standard controls in the Microsoft .NET Framework.
Examples of .NET Framework components are calendars, graphing, spell checking, advanced grids and browsers.
LANSA provides support for the use of .NET Framework components and controls in Visual LANSA projects.
