VirtualPathExtension Class

Contains the service's virtual path when the service is hosted in Internet Information Services (IIS) or Windows Process Activation Service (WAS).

Namespace:  System.ServiceModel.Activation
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public sealed class VirtualPathExtension : IExtension<ServiceHostBase>

This extension is only present for services hosted in IIS or WAS. Services can determine whether they are hosted in IIS or WAS by retrieving this extension from their ServiceHostBase, as shown in the following example.

The following example shows how to recover the VirtualPathExtension from the service host and return a value that it is hosted in IIS or WAS.

bool isHosted = false;
ServiceHostBase host = OperationContext.Current.Host;
VirtualPathExtension vpe = host.Extentions.Find<VirtualPathExtension>();

if( vpe != null )
   isHosted = true;
Console.WriteLine("Is the service hosted in IIS or WAS? {0}", isHosted);
