System.ComponentModel.Design Namespace

Contains classes that developers can use to build custom design-time behavior for components and user interfaces for configuring components at design time. The design time environment provides systems that enable developers to arrange components and configure their properties. Some components may require specific design-time only behavior to function properly in a design time environment. It may also be valuable to provide custom user interfaces which assist developers in configuring components or the values of complex data types. The classes and interfaces defined within this namespace can be used to build design-time behavior for components, access design-time services, and implement customized design-time configuration interfaces.
