Service Implementation:

namespace PresidentsService
{
public class PresidentsService : IPresidentsService
{
private List _presidents;

internal List Presidents
{
get
{
// If there aren't any presidents in our list, populate with samples and return
_presidents = _presidents ?? new List(SampleData.SamplePresidents);
return _presidents;
}
}
public List GetAllPresidentsXml()

Service Web.Config:

Client Web.Config:

And I am calling the service by a ASP.NET page by below way:

So, I am not able to access the service and getting above mentioned error message.

but I can confirm that the service is working well in SOAP UI. Also if I consume this service by below way I can able to get response as well.

string sURL = "http://localhost:63024/PresidentsService.svc/presidents";
WebRequest wrGETURL;
wrGETURL = WebRequest.Create(sURL);
wrGETURL.Method = "GET";
wrGETURL.ContentType = @"application/xml; charset=utf-8";
HttpWebResponse webresponse = wrGETURL.GetResponse() as HttpWebResponse;
Encoding enc = System.Text.Encoding.GetEncoding("utf-8");
StreamReader loResponseStream = new StreamReader(webresponse.GetResponseStream(), enc);
string strResult = loResponseStream.ReadToEnd();
loResponseStream.Close();
webresponse.Close();
Response.Write(strResult);

So what is the issue? Please help me.
