C # create site in IIS programmatically in asp.net project

I am trying to create a site in IIS using Microsoft.Web.Administration dll in C #. I am using the following code

using (var serverManager = new ServerManager())
        {
            ApplicationPool pool = serverManager.ApplicationPools.Add(ClientDomain);
            pool.ManagedRuntimeVersion = "v4.0";
            Site site = serverManager.Sites.Add(SiteName, httpProtocol, httpBindingInformation, physicalPath);
            site.Bindings.Add(httpsBindingInformation, httpsProtocol);
            serverManager.CommitChanges();
        }

      

        
        
        
      

    

I am getting the following exception: "Method or operation not implemented" when I run the code from an asp.net project, but if the same code is run from a console project, it works fine. Following is the details of the exception

   at Microsoft.Web.Administration.Interop.IAppHostProperty.get_Value()
   at Microsoft.Web.Administration.ConfigurationElement.GetPropertyValue(IAppHostProperty property)
   at Microsoft.Web.Administration.ConfigurationElement.GetAttributeValue(String attributeName)
   at Microsoft.Web.Administration.Binding.get_CertificateHash()
   at Microsoft.Web.Administration.BindingCollection.Add(Binding binding)
   at Microsoft.Web.Administration.BindingCollection.Add(String bindingInformation, String bindingProtocol)
   at TestProject.BLL.CRMSiteManagement.CRMSiteIISSetup.Process() in e:\CRMSiteManagement\CRMSiteIISSetup.cs:line 35
   at TestProject.BLL.CRMSiteManagement.CRMSiteService.CreateNewCRMSite(CRMSite newSite) in e:CRMSiteManagement\CRMSiteService.cs:line

      

        
        
        
      

    

It seems to be a rights issue, but I don't know how to fix it. Update 1: The error goes along the following line of code on localhost

site.Bindings.Add(httpsBindingInformation, httpsProtocol);
