System.EnterpriseServices Namespace ()

.NET Framework Class Library

System.EnterpriseServices Namespace

The System.EnterpriseServices namespace provides an important infrastructure for enterprise applications. COM+ provides a services architecture for component programming models deployed in an enterprise environment. This namespace provides .NET objects with access to COM+ services making the .NET Framework objects more practical for enterprise applications.

For information about using System.EnterpriseServices, see Writing Serviced Components

	LoadBalancingSupportedAttribute	Determines whether the component participates in load balancing, if the component load balancing service is installed and enabled on the server.
	MustRunInClientContextAttribute	Forces the attributed object to be created in the context of the creator, if possible. This class cannot be inherited.
	ObjectPoolingAttribute	Enables and configures object pooling for a component. This class cannot be inherited.
	PrivateComponentAttribute	Identifies a component as a private component that is only seen and activated by components in the same application. This class cannot be inherited.
	RegistrationConfig	Provides configuration information for installing assemblies into the COM+ catalog.
	RegistrationErrorInfo	Retrieves extended error information about methods related to multiple COM+ objects. This also includes methods that install, import, and export COM+ applications and components. This class cannot be inherited.
	RegistrationException	The exception that is thrown when a registration error is detected.
	RegistrationHelper	Installs and configures assemblies in the COM+ catalog. This class cannot be inherited.
	RegistrationHelperTx	Infrastructure. Used by the .NET Framework infrastructure to install and configure assemblies in the COM+ catalog while maintaining a newly established transaction.
	ResourcePool	Stores objects in the current transaction. This class cannot be inherited.
	SecureMethodAttribute	Ensures that the infrastructure calls through an interface for a method or for each method in a class when using the security service. Classes need to use interfaces to use security services. This class cannot be inherited.
	SecurityCallContext	Describes the chain of callers leading up to the current method call.
	SecurityCallers	Provides an ordered collection of identities in the current call chain.
	SecurityIdentity	Contains information that regards an identity in a COM+ call chain.
	SecurityRoleAttribute	Configures a role for an application or component. This class cannot be inherited.
	ServiceConfig	Specifies and configures the services that are to be active in the domain which is entered when calling Enter or creating an Activity. This class cannot be inherited.
	ServicedComponent	Represents the base class of all classes using COM+ services.
	ServicedComponentException	The exception that is thrown when an error is detected in a serviced component.
	ServiceDomain	Allows a code segment identified by Enter and Leave to run in its own context and behave as if it were a method that is called on an object created within the context. This class cannot be inherited.
	SharedProperty	Accesses a shared property. This class cannot be inherited.
	SharedPropertyGroup	Represents a collection of shared properties. This class cannot be inherited.
	SharedPropertyGroupManager	Controls access to shared property groups. This class cannot be inherited.
	SynchronizationAttribute	Sets the synchronization value of the component. This class cannot be inherited.
	TransactionAttribute	Specifies the type of transaction that is available to the attributed object. Permissible values are members of the TransactionOption enumeration.

Structures

	Structure	Description
	BOID	Represents the unit of work associated with a transaction. This structure is used in XACTTRANSINFO.
	XACTTRANSINFO	Represents a structure used in the ITransaction interface.

Interfaces

	Interface	Description
	IAsyncErrorNotify	Implements error trapping on the asynchronous batch work that is submitted by the Activity object.
	IPlaybackControl	Functions in Queued Components in the abnormal handling of server-side playback errors and client-side failures of the Message Queuing delivery mechanism.
	IProcessInitControl	Supports setting the time-out for the Startup method.
	IProcessInitializer	Supports methods that can be called when a COM component starts up or shuts down.
	IRegistrationHelper	Installs and configures assemblies in the COM+ catalog.
	IRemoteDispatch	Infrastructure. Implemented by the ServicedComponent class to determine if the AutoCompleteAttribute class attribute is set to true or false for a remote method invocation.
	IServiceCall	Implements the batch work that is submitted through the activity created by Activity.
	IServicedComponentInfo	Infrastructure. Implemented by the ServicedComponent class to obtain information about the component via the GetComponentInfo method.
	ITransaction	Corresponds to the Distributed Transaction Coordinator (DTC) ITransaction interface and is supported by objects obtained through ContextUtil..::.Transaction.

Delegates

	Delegate	Description
	ResourcePool..::.TransactionEndDelegate	Represents the method that handles the ending of a transaction.

Enumerations

	Enumeration	Description
