Unable to launch the IIS Express Web Server after using Microsoft.Web.Administration

Question

I have been playing around with Microsoft.Web.Administration and I have had the following code run in my settup:

            {
                using (ServerManager serverManager = new ServerManager())
                {
                    foreach (Site site in serverManager.Sites)
                    {
                        site.Delete();
                    }

                    foreach (var applicationPool in serverManager.ApplicationPools)
                    {
                        applicationPool.Delete();
                    }

                    serverManager.CommitChanges();
                }
            }

Today I am not able, when create a new site in visual studio to start IIS Express.

I have uninstalled and installed it again with same results.

C:\Users\s093294>"C:\Program Files\IIS Express\iisexpress.exe" /trace:error Starting IIS Express ... Process Model Shutdown called Unable to start iisexpress.

The object identifier does not represent a valid object. For more information about the error, run iisexpress.exe with the tracing switch enabled (/trace:error).

Any suggestions?

Answer 1

probably your applicationhost.config file (located in %userprofile%\documents\iisexpress\config) was corrupted. Take a backup of this applicationhost.config file and delete it and then re-create the site from visual studio. (IIS Express would recreate the config file)
