Not able to create dynamic web application in IIS7 and above

Question

Not able to view application in IIS after successfully calling below method:

ServerManager serverMgr = new ServerManager();
Configuration config = serverMgr.GetApplicationHostConfiguration();
ConfigurationSection isapiCgiRestrictionSection = config.GetSection("system.webServer/security/isapiCgiRestriction");
ConfigurationElementCollection isapiCgiRestrictionCollection = isapiCgiRestrictionSection.GetCollection();
//ConfigurationElement addElement = isapiCgiRestrictionCollection.CreateElement("add");
//addElement["path"] = @"C:\Inetpub\wwwroot\";
//addElement["allowed"] = true;
//addElement["groupId"] = @"ContosoGroup";
//addElement["description"] = @"Contoso Extension";
//isapiCgiRestrictionCollection.Add(addElement);
//serverMgr.CommitChanges();

Site defaultSite = serverMgr.Sites["PharmaConnect"];
defaultSite.Applications.Add("/blogs3", @"C:\inetpub\wwwroot\blogs1");
serverMgr.CommitChanges();

I don't know how to create dynamically sub domain though c# code. We just tried to implement above. But unable to view application/virtual directory in iis.

I have tried this, but didn't get success.

You can create Dynamic Web Application in IIS by Following Code and Make sure that Your Visual Studio is Open in Administrator Mode because i was found Access Denied Issue while Creating WebApplication in IIS

-- Web Config file

<!---Default format is IIS://<your server name>/W3SVC-->
    <add key="metabasePath" value="IIS://JAYDEV/W3SVC"/>
    <!--Framework version of newly created website-->
    <add key="frameworkVersion" value="4.0"/>
    <!---Local path of newly created website -->
    <add key="defaultFileLocation" value="C:\inetpub\wwwroot\Dynamic1"/>
    <!---Application Pool of newly created website-->
    <add key="defaultAppPool" value="DynamicPool"/>

-- C# Code

public ActionResult DynamicWeb()
{

            try
            {


                string metabasePath = Convert.ToString(ConfigurationManager.AppSettings["metabasePath"]);
                string frameworkVersion = Convert.ToString(ConfigurationManager.AppSettings["frameworkVersion"].ToString());
                string physicalPath = Convert.ToString(ConfigurationManager.AppSettings["defaultFileLocation"].ToString());
                string defaultAppPool = ConfigurationManager.AppSettings["defaultAppPool"].ToString();//Host Header Info
                object[] hosts = new object[2];
