.NET Framework 2.0 Hosting Interfaces

This section describes the interfaces that unmanaged hosts can use to integrate the common language runtime (CLR) into their applications. The information pertains to the .NET Framework version 2.0 and later versions. These interfaces enable the host to control many more aspects of the runtime than was possible in versions 1.0 and 1.1, and provide much tighter integration between the CLR and the host's execution model.

In the .NET Framework version 1.0 and 1.1, the hosting model enabled an unmanaged host to load the CLR into a process, to configure certain settings, and to receive event notifications. However, in general, the host and the CLR ran independently in that process. In the .NET Framework version 2.0 and later versions, new layers of abstraction let the host provide many of the resources currently provided by the types in the Win32 assembly, and extend the set of capabilities that the host can configure.

IActionOnCLREvent Interface

Provides a method that performs a callback for a registered event.

IApartmentCallback Interface

Provides methods for making callbacks within an apartment.

IAppDomainBinding Interface

Provides methods for setting run-time configuration.

ICatalogServices Interface

Provides methods for cataloging services. (This interface supports the .NET Framework infrastructure and is not intended to be used directly from your code.)

ICLRAssemblyIdentityManager Interface

Provides methods that support communication between the host and the CLR about assemblies.

ICLRAssemblyReferenceList Interface

Manages a list of assemblies that are loaded by the CLR and not by the host.

ICLRControl Interface

Provides methods for the host to gain access to, and configure various aspects of, the CLR.

ICLRDebugManager Interface

Provides methods that enable a host to associate a set of tasks with an identifier and a friendly name.

ICLRErrorReportingManager Interface

Provides methods that enable the host to configure custom heap dumps for error reporting.

ICLRGCManager Interface

Provides methods that enable a host to interact with the CLR's garbage collection system.

ICLRHostBindingPolicyManager Interface

Provides methods for the host to evaluate and communicate changes in policy information for assemblies.

ICLRHostProtectionManager Interface

Enables the host to block specific managed classes, methods, properties, and fields from running in partially trusted code.

ICLRIoCompletionManager Interface

Implements a callback method that enables the host to notify the CLR of the status of specified I/O requests.

ICLRMemoryNotificationCallback Interface

Enables the host to report memory pressure conditions using an approach similar to that of the Win32 CreateMemoryResourceNotification function.

ICLROnEventManager Interface

Provides methods that enable the host to register and unregister callbacks for CLR events.

ICLRPolicyManager Interface

Provides methods that enable the host to specify policy actions to be taken in the event of failures and timeouts.

ICLRProbingAssemblyEnum Interface

Provides methods that enable the host to get the probing identities of an assembly by using the assembly's identity information that is internal to the CLR, without needing to create or understand that identity.

ICLRReferenceAssemblyEnum Interface

Provides methods that enable the host to manipulate the set of assemblies referenced by a file or stream using assembly identity data that is internal to the CLR, without needing to create or understand those identities.

ICLRRuntimeHost Interface

Provides capabilities similar to ICorRuntimeHost, with an additional method to set the host control interface.

ICLRSyncManager Interface

Provides methods for the host to get information about requested tasks and to detect deadlocks in its synchronization implementation.

ICLRTask Interface

Provides methods that enable the host to make requests of the CLR, or to provide notification to the CLR about the associated task.

ICLRTaskManager Interface

Provides methods that enable the host to request explicitly that the CLR create a new task, get the currently executing task, and set the geographic language and culture for the task.

ICLRValidator Interface

Provides methods for validating portable executable (PE) images and reporting validation errors.

ICorConfiguration Interface

Provides methods for configuring the CLR.

ICorThreadpool Interface

Provides methods for accessing the thread pool.

IDebuggerInfo Interface

Provides methods for obtaining information about the state of the debugging services.

IDebuggerThreadControl Interface

Provides methods for notifying the host about the blocking and unblocking of threads by the debugging services.

IGCHost Interface

Provides methods for obtaining information about the garbage collection system and for controlling some aspects of garbage collection.

IGCHostControl Interface

Provides a method that enables the garbage collector to request the host to change the limits of virtual memory.

IGCThreadControl Interface

Provides methods for participating in the scheduling of threads that would otherwise be blocked for garbage collection.

IHostAssemblyManager Interface

Provides methods that enable a host to specify sets of assemblies that should be loaded by the CLR or by the host.

IHostAssemblyStore Interface

Provides methods that enable a host to load assemblies and modules independently of the CLR.

IHostAutoEvent Interface

Provides a representation of an auto-reset event implemented by the host.

IHostControl Interface

Provides methods for configuring the loading of assemblies, and for determining which hosting interfaces the host supports.

IHostCrst Interface

Serves as the host's representation of a critical section for threading.

IHostGCManager Interface

Provides methods that notify the host of events in the garbage collection mechanism implemented by the CLR.

IHostIoCompletionManager Interface

Provides methods that enable the CLR to interact with I/O completion ports provided by the host.

IHostMalloc Interface

Provides methods for the CLR to request fine-grained allocations from the heap through the host.

IHostManualEvent Interface

Provides the host's implementation of a representation of a manual reset event.

IHostMemoryManager Interface

Provides methods for the CLR to make virtual memory requests through the host, instead of using the standard Win32 virtual memory functions.

IHostPolicyManager Interface

Provides methods that notify the host of the actions the CLR performs in case of aborts, timeouts, or failures.

IHostSecurityContext Interface

Enables the CLR to maintain security context information implemented by the host.

IHostSecurityManager Interface

Provides methods that enable access to, and control over, the security context of the currently executing thread.

IHostSemaphore Interface

Provides a representation of a semaphore implemented by the host.

IHostSyncManager Interface

Provides methods for the CLR to create synchronization primitives by calling the host, instead of using the Win32 synchronization functions.

IHostTask Interface

Provides methods that enable the CLR to communicate with the host to manage tasks.

IHostTaskManager Interface

Provides methods that enable the CLR to work with tasks through the host instead of using the standard operating system threading or fiber functions.

IHostThreadPoolManager Interface

Provides methods for the CLR to configure the thread pool and to queue work items to the thread pool.

IManagedObject Interface

Provides methods for controlling a managed object.

IObjectHandle Interface

Provides a method for unwrapping marshal-by-value objects from indirection.

ITypeName Interface

Provides methods for obtaining type name information. (This interface supports the .NET Framework infrastructure and is not intended to be used directly from your code.)

ITypeNameBuilder Interface

Provides methods for building a type name. (This interface supports the .NET Framework infrastructure and is not intended to be used directly from your code.)

ITypeNameFactory Interface

Provides methods for deconstructing a type name. (This interface supports the .NET Framework infrastructure and is not intended to be used directly from your code.)

IValidator Interface

Provides methods for validating portable executable (PE) images and reporting validation errors.
