License Class

Provides the abstract base class for all licenses. A license is granted to a specific instance of a component.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
public abstract class License : IDisposable

NoteNote:

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

All components must call Dispose for the licenses they grant when the component is disposed or finalized.

Notes to Inheritors:

When you inherit from License, you must override the following members: LicenseKey and Dispose.

For more information on licensing, see How to: License Components and Controls.
