creating primary keys in microsoft dynamics crm

Question

Hi,
I wanted to know how to create primary key attributes for custom entities in microsoft dynamics crm.

Answer 1

The unique key is automatically created for you when you create a custom entity - new_customentitynameID - it's a guid. -

Adding other attributes is done through the CRU administration UI.

using System;
using System.Collections.Generic;

using System.Web.UI;
using System.Web.UI.WebControls;
using Microsoft.Crm.Sdk;

using Microsoft.Win32;
namespace WebApplication20
{
    public partial class _Default : System.Web.UI.Page
    {
        public string orgname;
        public string crmurl;
        public string metaurl;
        public bool offline;

        protected void Page_Load(object sender, EventArgs e)
        {
            #region CRM URLs and Organization Name

            //Determine Offline State from Host Name
            Response.Write(Request.Url.Host.ToString());
            if (Request.Url.Host.ToString() == "127.0.0.1")
            {
                offline = true;

                //Retrieve the Port and OrgName from the Registry
                RegistryKey regkey = Registry.CurrentUser.OpenSubKey("Software\\Microsoft\\MSCRMClient");
                orgname = regkey.GetValue("ClientAuthOrganizationName").ToString();
                string portnumber = regkey.GetValue("CassiniPort").ToString();

                //Construct the URLs
                string baseurl = "http://localhost:" + portnumber + "/mscrmservices/2007/";
                crmurl = baseurl + "crmservice.asmx";
                metaurl = baseurl + "metadataservice.asmx";
            }
            else
            {
                offline = false;

                //Retrieve the URLs from the Registry
                RegistryKey regkey = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\MSCRM");
                string ServerUrl = regkey.GetValue("ServerUrl").ToString();
                crmurl = ServerUrl + "/2007/crmservice.asmx";
                metaurl = ServerUrl + "/2007/metadataservice.asmx";
               
                //Retrieve the Query String from the current URL
                if (Request.QueryString["orgname"] == null)

                    {
                        orgname = Request.Url.Segments[1].TrimEnd('/').ToLower();
                    }

                        int start = url.IndexOf("://") + 3;
                        orgname = url.Substring(start, url.IndexOf(".") - start);
                    }

            }

            #endregion

            using (new CrmImpersonator())

                    token = CrmAuthenticationToken.ExtractCrmAuthenticationToken(Context, orgname);

            Response.Write("Done");

        }
    }
}

But it failed with the following error:
