Hi Ron... this is working like a charm.

However, is there a way I can use the WorkflowServiceHostFactory while using this VirtualPathProvider?

Any idea, please let me know.

Thanks!

To answer the question I posted, I found that a wsHttp service is created for the xamlx at http://<host>/xaml/<wfname>.xmalx/System.ServiceModel.Activities_IWorkflowInstanceManagement

@ashish The service would still emit tracking events in the monitoring store but as you point out AppFabric would not display it as a service or offer control operations on it.

i am wondering how we would use appfabric with this type of sitiuation, in case we want to monitor or persist a service, since these services are not visible through IIS in Appfabric dashboard

Thanks Jim! No I don't know why returning null works.

Thanks for the great sample. I found that adding the GetCacheDependency override allows you to avoid having the xaml folder, but using sample code gets an error. The link forums.asp.net/.../1289756.aspx said returning null works, which it does. Do you have insight as to why that works?

public override CacheDependency GetCacheDependency(string virtualPath,

IEnumerable virtualPathDependencies,

DateTime utcStart)

{

if (IsPathVirtual(virtualPath))

return null;

else

return Previous.GetCacheDependency(virtualPath, virtualPathDependencies, utcStart);

}
