Windows Azure creating virtual directory to local storage

问题

I need a help with creating virtual directory pointing to local storage in Windows Azure (production environment). I can set up a virtual directory manually but it is being erased every time Azure is restarted. The clue is to create the virtual directory via config file when I upload a package of my project on Azure. The question is how to create such directory so that it is pointing to local storage.

Thx in advance for any suggestions.

Best Regards,

I suggest you create the virtual directory by interacting with IIS in the WebRole's OnStart method:

public class WebRole : RoleEntryPoint
{
    public override bool OnStart()
    {
        // Connect to the IIS site.
        using (var manager = new Microsoft.Web.Administration.ServerManager())
        { 
                var localResourcePath = RoleEnvironment.GetLocalResource("MyResource").RootPath;

            // Add to the root application.
            var rootSite = manager.Sites[RoleEnvironment.CurrentRoleInstance.Id + "_Web"];
            var rootApplication = rootSite.Applications["/"];
                rootApplication.VirtualDirectories.Add("/myVdir", localResourcePath);

                // Save
            manager.CommitChanges();
        }

        ...
    }
}

If I'm right you'll need to set the execution context to elevated for this to work. You can do this in the ServiceDefintion.csdef:

<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="MyProject" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2012-05.1.7">
  <WebRole name="MyRole" vmsize="Small" enableNativeCodeExecution="true">
    <Runtime executionContext="elevated" />
    ...
  </WebRole>
</ServiceDefinition>

Note: You'll need to reference Microsoft.Web.Administration.dll (C:\Windows\System32\inetsrv)
