Is there a .NET Library or API to interact with/Edit the IIS Metabase?

...or am I stuck rolling my own "XML chopping" functions. I'd like to create a small tasktray app so I can quickly re-point a Virual Directory to one of several of folders on my harddisk.

Bit of background:

I have 3 different svn branches of our code base on my dev machine.

Current Production Branch    ( C:\Projects\....\branches\Prod\ )
Next Release Canidate Branch ( C:\Projects\....\branches\RCX\ )
Trunk                        ( C:\Projects\....\trunk\ )

Our app integrates with a 3rd party CMS which I've installed at

http://localhost/cms/

In order to work our app has to live at the same root directory. so:

http://localhost/app/

Depending on the branch I'm working on, I'm re-pointing the /app/ directory to one of the 3 paths listed above by going into IIS Manager. Just thought it'd be handy to have a quick-app to do it for me.

Ok...this isn't a tray app but you can run it from the command line. Just change the physical paths as necessary:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.DirectoryServices;

namespace Swapper
{
  class Program
  {
    static void Main(string[] args)
    {
      using (DirectoryEntry appRoot = 
               new DirectoryEntry("IIS://Localhost/W3SVC/1/root/app"))
      {
        switch (args[0].ToLower())
        {
          case "prod":
            appRoot.Properties["Path"].Value = @"e:\app\prod";
            appRoot.CommitChanges();
            break;

          case "rcx":
            appRoot.Properties["Path"].Value = @"e:\app\rcx";
            appRoot.CommitChanges();
            break;

          case "trunk":
            appRoot.Properties["Path"].Value = @"e:\app\trunk";
            appRoot.CommitChanges();
            break;

          default:
            Console.WriteLine("Don't know");
            break;
        }
      }
    }
  }
}

Then run as in:

C:\>swapper prod
C:\>swapper rcx

etc
