I couldn't bring up the link you have to Chris Adams blog...however, you can do it using the Directory Service built into .NET 2.0...I did it for a console app, where I allowed the user to type in a full/partial name of an application pool to recycle...(or they could specify no parameters, and they would get a full list of the application pools)

Here's the code:


static void Main(string[] args)
{
DirectoryEntry appPools = new DirectoryEntry("IIS://localhost/W3SVC/AppPools");

if (appPools == null)
{
Console.WriteLine("There were no App Pools located");
return;
}

if (args.Length == 0)
{
Console.WriteLine("Please specify an App Pool to recycle: ");

foreach (DirectoryEntry row in appPools.Children)
{
Console.WriteLine(row.Name.ToString());
}

return;
}

int restartCount = 0;

foreach (DirectoryEntry row in appPools.Children)
{
if (row.Name.ToLower().IndexOf(args[0]) > -1)
{
try
{
row.Invoke("Recycle", null);
restartCount += 1;
Console.WriteLine("Recycling App Pool: " + row.Name);
}
catch (Exception ex)
{
Console.WriteLine("There was an error recycling the App Pool: " + row.Name);
Console.WriteLine("Details: " + ex.Message);
}
}
}

if (restartCount == 0)
{
Console.WriteLine("Could not locate the App Pool specified.");
foreach (DirectoryEntry row in appPools.Children)
{
Console.WriteLine(row.Name.ToString());
}
}

}
