Syntax

public abstract class License : Freezable<LicenseProviderAttribute>

Remarks

A License is created and signed by LicensePublisher which normally implemented as web service. The LicenseClient communicates with the LicensePublisher, gets the published license and stores it somewhere that can be loaded by the LicenseProviderAttribute declared as assembly attribute. To determine whether an assembly can be granted a valid license, the license provider attributes are retrieved to provide an instance of License object containing a collection of LicenseItem objects. The validation is then performed on the License object and the LicenseItem object matching the specified license item name.

Before performing the validation on the LicenseItem object, the license provider seals the License object by setting its IsFrozen property to true. Any attempting to modify the License object throws an System.InvalidOperationException. All derived classes should respect this rule by calling VerifyFrozenAccess() in all public methods and property setters that might modify the object.
