Connect to CRM Online or On-premise using C# SDK

Arun Potti CRM, CRM 2015, MS CRM 2013, Others

Follow the below Steps, to connect CRM Online or On-Premise using C#,

Step 1: Include the below References in your project, you can get the same from Latest SDK. Open SDK and goto the path, SDK –> Bin for the dlls

Microsoft.Crm.Sdk.Proxy
Microsoft.Xrm.Sdk

Step 2: Include the below Framework Assemblies in your project,

System.Runtime.Serialization
System.ServiceModel

Reference Manager - ConnectToCRM

Step 3: Finally add the below namespaces in your class file,

using Microsoft.Crm.Sdk.Messages;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Client;
using System.ServiceModel.Description;

Your References will be looking like this in Solution Explorer,

References

Step 4: Use the Below Method to your code for establishing CRM Connection, which consists of 3 parameters

Parameter Name Usage
UserName Online: Provide office 365 userid
On-Premise: Provide domain\username
Password Provide password
SoapOrgServiceUri Open Mscrm online or on-premise,
Goto Microsoft Dynamics CRM -> Settings ->
Customizations -> Developer Resources.
Under Service Endpoints -> Organization Service.
Ex: https://<OrgName>.api.crm5.dynamics.com/
XRMServices/2011/ Organization.svc		 
static IOrganizationService _service;

public static void ConnectToMSCRM(string UserName,string Password,string SoapOrgServiceUri)
{
    try
    {
        ClientCredentials credentials = new ClientCredentials();
        credentials.UserName.UserName = UserName;
        credentials.UserName.Password = Password;
        Uri serviceUri = new Uri(SoapOrgServiceUri);
        OrganizationServiceProxy proxy = new OrganizationServiceProxy(serviceUri, null, credentials, null);
        proxy.EnableProxyTypes();
        _service = (IOrganizationService)proxy;
    }
    catch (Exception ex)
    {
        Console.WriteLine("Error while connecting to CRM " + ex.Message);
        Console.ReadKey();
    }
}

Step 5: For this example, I am using Console application. Finally the code looks like this,

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Crm.Sdk.Messages;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Client;
using System.ServiceModel.Description;
namespace ConnectToCRM
{
   class Program
   {
       static IOrganizationService _service;
        static void Main(string[] args)
       {
           ConnectToMSCRM("arunpotti@XYZORG.onmicrosoft.com", "XYZORGPassword", "https://XYZORG.api.crm5.dynamics.com/XRMServices/2011/Organization.svc");
           Guid userid = ((WhoAmIResponse)_service.Execute(new WhoAmIRequest())).UserId;
           if (userid != Guid.Empty)
           {
               Console.WriteLine("Connection Established Successfully");
               Console.ReadKey();
           }
       }
       public static void ConnectToMSCRM(string UserName,string Password,string SoapOrgServiceUri)
       {
           try
           {
               ClientCredentials credentials = new ClientCredentials();
               credentials.UserName.UserName = UserName;
                credentials.UserName.Password = Password;
               Uri serviceUri = new Uri(SoapOrgServiceUri);
               OrganizationServiceProxy proxy = new OrganizationServiceProxy(serviceUri, null, credentials, null);
               proxy.EnableProxyTypes();
               _service = (IOrganizationService)proxy;
           }
           catch (Exception ex)
           {
               Console.WriteLine("Error while connecting to CRM " + ex.Message);
               Console.ReadKey();
           }
       }
   }
}

Step 6: Build the project and Click on Start, you can see the below output

  14. Arun,
    Thank you for this amazing article. For a Noob CRM developer, the MS Documentation and SDK examples are completely unfathomable! I couldn’t get the SDK sample programs to connect to my CRM org, and deciphering the thousands of lines of code was impossible. With your clear description of how to set up the references and assemblies, I got connected to CRM in five minutes 🙂
    Thanks,
    Tony
