Assembly: System.AddIn.Contract (in System.AddIn.Contract.dll)
Clients of an object that implements IContract call the method to notify the object that the client requires access to the contract. An IContract is guaranteed to be usable as long as at least one lifetime token that it passed to a client has not been revoked.
To revoke a contract, clients call the RevokeLifetimeToken method.
