System.EnterpriseServices Namespace

Provides .NET objects with access to COM+ services making the .NET Framework objects more practical for enterprise applications.

Classes

Activity	Creates an activity to do synchronous or asynchronous batch work that can use COM+ services without needing to create a COM+ component. This class cannot be inherited.
ApplicationAccessControlAttribute	Specifies access controls to an assembly containing ServicedComponent classes.
ApplicationActivationAttribute	Specifies whether components in the assembly run in the creator's process or in a system process.
ApplicationIDAttribute	Specifies the application ID (as a GUID) for this assembly. This class cannot be inherited.
ApplicationNameAttribute	Specifies the name of the COM+ application to be used for the install of the components in the assembly. This class cannot be inherited.
ApplicationQueuingAttribute	Enables queuing support for the marked assembly and enables the application to read method calls from Message Queuing queues. This class cannot be inherited.
AutoCompleteAttribute	Marks the attributed method as an AutoComplete object. This class cannot be inherited.
BYOT	Wraps the COM+ ByotServerEx class and the COM+ DTC interfaces ICreateWithTransactionEx and ICreateWithTipTransactionEx. This class cannot be inherited.
ComponentAccessControlAttribute	Enables security checking on calls to a component. This class cannot be inherited.
COMTIIntrinsicsAttribute	Enables you to pass context properties from the COM Transaction Integrator (COMTI) into the COM+ context.
ConstructionEnabledAttribute	Enables COM+ object construction support. This class cannot be inherited.
ContextUtil	Obtains information about the COM+ object context. This class cannot be inherited.
DescriptionAttribute	Sets the description on an assembly (application), component, method, or interface. This class cannot be inherited.
EventClassAttribute	Marks the attributed class as an event class. This class cannot be inherited.
EventTrackingEnabledAttribute	Enables event tracking for a component. This class cannot be inherited.
ExceptionClassAttribute	Sets the queuing exception class for the queued class. This class cannot be inherited.
IISIntrinsicsAttribute	Enables access to ASP intrinsic values from GetNamedProperty(String). This class cannot be inherited.
InterfaceQueuingAttribute	Enables queuing support for the marked interface. This class cannot be inherited.
JustInTimeActivationAttribute	Turns just-in-time (JIT) activation on or off. This class cannot be inherited.
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	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(ServiceConfig) 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(ServiceConfig) 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.

Structs

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

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(Object) 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	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	Implemented by the ServicedComponent class to obtain information about the component via the GetComponentInfo(Int32, String[]) method.
ITransaction	Corresponds to the Distributed Transaction Coordinator (DTC) ITransaction interface and is supported by objects obtained through Transaction.

Enums

AccessChecksLevelOption	Specifies the level of access checking for an application, either at the process level only or at all levels, including component, interface, and method levels.
ActivationOption	Specifies the manner in which serviced components are activated in the application.
AuthenticationOption	Specifies the remote procedure call (RPC) authentication mechanism. Applicable only when the ActivationOption is set to Server.

PropertyReleaseMode	Specifies the release mode for the properties in the new shared property group.
SxsOption	Indicates how side-by-side assemblies are configured for ServiceConfig.
SynchronizationOption	Specifies the type of automatic synchronization requested by the component.
ThreadPoolOption	Indicates the thread pool in which the work, submitted by Activity, runs.
TransactionIsolationLevel	Specifies the value of the TransactionAttribute.

TransactionVote	Specifies the values allowed for transaction outcome voting.

Delegates

ResourcePool.TransactionEndDelegate

Represents the method that handles the ending of a transaction.
