c# - How can I programmatically stop or start a website in IIS (6.0 and 7.0) using MsBuild?

Question

I have Windows Server 2003 (IIS 6.0) and Windows Server 2008 (IIS 7.0) servers, and I use MSBuild for deploying web applications.

I need to do a safe deploy, and do this:

1. Stop a website in IIS 6 (or an Application in IIS 7), not stop AppPool.

2. Check if the website is stopped; not running.

3. If the website is stopped, do another task for deploy.

4. Start the website IIS 6 (or Application in IIS 7),

How can I achieve this?

Update: Key for me: IIS6WebSite and IIS6AppPool (and for IIS7), do wait for stopped status when try Stop Website or AppPool?

When I execute Stop Action for Website (or Stop Action for AppPool), I need be sure 100% that Website is stopped, and then, and only if Website is Stopped, I can execute other targets.

By adding a reference to Microsoft.Web.Administration (which can be found inX:WindowsSystem32inetsrv, or your systems equivalent) you can achieve nice managed control of the situation with IIS7, as sampled below:

namespace StackOverflow
{
    using System;
    using System.Linq;
    using Microsoft.Web.Administration;

    class Program
    {
        static void Main(string[] args)
        {
            var server = new ServerManager();
            var site = server.Sites.FirstOrDefault(s => s.Name == "Default Web Site");
            if (site != null)
            {
                //stop the site...
                site.Stop();
                if (site.State == ObjectState.Stopped)
                {
                    //do deployment tasks...
                }
                else
                {
                    throw new InvalidOperationException("Could not stop website!");
                }
                //restart the site...
                site.Start();
            }
            else
            {
                throw new InvalidOperationException("Could not find website!");
            }
        }
    }
}

Obviously tailor this to your own requirements and through your deployment build script execute the resulting application.

Enjoy. :)
