Classes
  ClassDescription
Public classContractExceptionFactory
Base class for contract exception factories. Implements chain of responsibility between concrete exception factories.
Public classContractExceptionInfo
This class holds the information from which the ContractExceptionFactory should create the exception.
Public classContractLocalizedTextProvider
Base class for contract error messages providers.
Public classContractServices
This class provides services supporting Contract aspects. By adding your own classes to the ExceptionFactory chain, you can change the way the exceptions are created when a contract is broken. By plugging into the LocalizedTextProvider chain, you can change the way the exception messages are generated. See the documentation for the classes for more details: ContractLocalizedTextProvider, ContractExceptionFactory.
