Hi,

I am fairly new to Project server on MS-Project 2010.
I am asked to use the basic web service to get the list of projects on MS-Project 2010 using the web services provided by MS-Project. I have included the web references to Project service and Login windows web service in the web application.

I am getting the following error:
"Unhandled communication fault occured"

I have written the following code:

try
            {
                string url = "http://sharepoint.xxx.com";

                ProjectService.Project p = new SharepointProjectTest1.ProjectService.Project();
                p.Url = url + "/_vti_bin/psi/Project.asmx";
                p.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;


                //Access the out of box LoginWindows web servcie   
                LoginWindowsService.LoginWindows loginWindows = new LoginWindowsService.LoginWindows();
                loginWindows.Url = url + "/_vti_bin/psi/LoginWindows.asmx";
                loginWindows.Credentials = System.Net.CredentialCache.DefaultCredentials;

                loginWindows.CookieContainer = new System.Net.CookieContainer();
                p.CookieContainer = loginWindows.CookieContainer;
                ProjectService.ProjectDataSet pjDataSet = p.ReadProjectList();
                
            }
                
            catch (System.Web.Services.Protocols.SoapException exx)
            {
                string StrException = exx.ToString();
                Response.Write(StrException);
            }
            catch (Exception ex)
            {

            }

Any help would be greatly appreciated.

Thanks.
