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 on using System.EnterpriseServices see Writing Serviced Components

Namespace hierarchy

Classes

Class Description
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 Allows security configuration for the library or server application housing the application. This class cannot be inherited.
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 ContextUtil.GetNamedProperty. 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.
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 regarding 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.

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.
IServiceCall Implements the batch work that is submitted through the activity created by Activity.
ITransaction Corresponds to the DTC ITransaction interface and is supported by objects obtained through ContextUtil.Transaction.

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.

Delegates

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

Enumerations

Enumeration Description
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.
BindingOption Indicates whether all work submitted by Activity should be bound to only one single-threaded apartment (STA). This enumeration has no impact on the multithreaded apartment (MTA).
ImpersonationLevelOption Specifies the level of impersonation allowed when calling targets of a server application.
InheritanceOption Indicates whether to create a new context based on the current context or on the information in ServiceConfig.
InstallationFlags Flags used with the RegistrationHelper class.
PartitionOption Indicates the context in which to run the COM+ partition.
PropertyLockMode Specifies the mode for accessing shared properties in the shared property group manager.
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.
TransactionOption Specifies the automatic transaction type requested by the component.
TransactionStatus Indicates the transaction status.
TransactionVote Specifies the values allowed for transaction outcome voting.
