LicenseContext Class

Specifies when you can use a licensed object and provides a way of obtaining additional services needed to support licenses running within its domain.

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

[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
public class LicenseContext : IServiceProvider

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.

This class provides the default LicenseContext. It implements only run-time support and does not support saved license keys.

Notes to Inheritors:

If you want to implement design-time license support, you must inherit from this class, and override the following members: UsageMode, GetSavedLicenseKey, GetService, and SetSavedLicenseKey. If you want to implement saved license keys, override the GetSavedLicenseKey and SetSavedLicenseKey methods.

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

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
