The System.Web.Hosting namespace provides the functionality for hosting ASP.NET applications from managed applications outside Microsoft Internet Information Services (IIS).

Classes

---

	Class	Description
	AppDomainFactory	Creates a new AppDomain instance for the Web application. This class cannot be inherited. This class was used by earlier versions of the .NET Framework than version 2.0, which uses the AppManagerAppDomainFactory class instead.
	AppDomainInfo	Provides information about the application domain.
	AppDomainInfoEnum	Provides access to an application domain.
	AppDomainProtocolHandler	Provides support for programmatic access to application domain protocols.
	ApplicationHost	Enables hosting of ASP.NET pages outside the Internet Information Services (IIS) application. This class enables the host to create application domains for processing ASP.NET requests.
	ApplicationInfo	Provides information about a running application. This class cannot be inherited.
	ApplicationManager	Manages ASP.NET application domains for an ASP.NET hosting application.
	AppManagerAppDomainFactory	Creates and stops application domains for a Web-application manager. This class cannot be inherited.
	HostingEnvironment	Provides application-management functions and application services to a managed application within its application domain. This class cannot be inherited.
	ISAPIRuntime	Manages HttpWorkerRequest objects in the .NET Framework. This class cannot be inherited.
	ProcessHost	This type supports the ASP.NET infrastructure and is not intended to be used directly from your code.
	ProcessHostFactoryHelper	This type supports the ASP.NET infrastructure and is not intended to be used directly from your code.
	ProcessProtocolHandler	This type supports the ASP.NET infrastructure and is not intended to be used directly from your code.
	SimpleWorkerRequest	Provides a simple implementation of the HttpWorkerRequest abstract class that can be used to host ASP.NET applications outside an Internet Information Services (IIS) application. You can employ SimpleWorkerRequest directly or extend it.
	VirtualDirectory	Represents a directory object in a virtual file or resource space.
	VirtualFile	Represents a file object in a virtual file or resource space.
	VirtualFileBase	Provides the core implementation for the VirtualFile and VirtualDirectory objects. An abstract class, it cannot be instantiated.
	VirtualPathProvider	Provides a set of methods that enable a Web application to retrieve resources from a virtual file system.

Interfaces

---

	Interface	Description
	IAdphManager	This type supports the ASP.NET infrastructure and is not intended to be used directly from your code.
	IAppDomainFactory	Defines a single method to create a new AppDomain instance for a Web application. This interface was used by .NET Framework versions earlier than 2.0; version 2.0 uses the IAppManagerAppDomainFactory interface instead.
	IAppDomainInfo	Provides information about the application domain.
	IAppDomainInfoEnum	Provides access to an application domain.
	IApplicationHost	This type supports the ASP.NET infrastructure and is not intended to be used directly from your code.
	IAppManagerAppDomainFactory	Defines a method used to create an AppDomain instance for a Web-application manager and a method used to stop all AppDomain instances for a Web-application manager.
	IISAPIRuntime	Defines methods used to create HttpWorkerRequest objects in the .NET Framework.
	IListenerChannelCallback	Provides listener-channel notifications from protocol handlers to the worker process framework. Also enables protocol handlers to access additional parameters, such as the ID of the listener channel.
	IPphManager	Provides stop and start control of listener channels.
	IProcessHost	This type supports the ASP.NET infrastructure and is not intended to be used directly from your code.
	IProcessHostFactoryHelper	This type supports the ASP.NET infrastructure and is not intended to be used directly from your code.
	IProcessHostIdleAndHealthCheck	This type supports the ASP.NET infrastructure and is not intended to be used directly from your code.
	IProcessHostSupportFunctions	Provides helper functions for the process host.
	IProcessPingCallback	Provides functionality to respond to a ping request.
	IRegisteredObject	Defines methods for objects that are managed by the hosting environment.
