Connecting to CRM Online (2013/2015)

Whenever i am going to extend CRM system or developing 3rd party party for CRM or a webservice. CRM Authentication is required to perform Create, Update, Delete or retrieve operations in CRM organisation therefore connection must be established and authenticated correctly to get hands on the CRM IOrganisation Service. Below is simple code to connect to CRM. i wrote this example in C# using windows console application and reading credentials from app.config.

<pre class="lang-cs prettyprint prettyprinted"><code><span class="pln">public static class CrmConnector
 public static IOrganizationService CreateCrmService()

 var userid = ((WhoAmIResponse)_orgService.Execute(new WhoAmIRequest())).UserId;
 if (userid != Guid.Empty)
 Console.WriteLine("Connection Established Successfully");
 Console.WriteLine("Connection couldn't established Successfully");
 return _orgService;

 static IOrganizationService _orgService;

 public static void ConnectToMscrm()
 var connectorUser = ConfigurationManager.AppSettings["connectorUser"]; //
 var connectorPassword = ConfigurationManager.AppSettings["connectorPassword"]; //password123
 var uri = ConfigurationManager.AppSettings["crmOrgServiceUrl"]; //
 //var homeRelamUrl = new Uri(ConfigurationManager.AppSettings["HomeRelamURL"]);

 var credentials = new ClientCredentials();
 credentials.UserName.UserName = connectorUser;
 credentials.UserName.Password = connectorPassword;

 var serviceUri = new Uri(uri);

 var orgProxy = new OrganizationServiceProxy(serviceUri, null, credentials, null);
 _orgService = (IOrganizationService)orgProxy;
 catch (Exception ex)
 //throw new Exception("Error Has Occurred while connecting to CRM Server " + ex.Message);
 Console.WriteLine("Error Has Occurred while connecting to CRM Server " + ex.Message);

Associate Many to Many Entity Record in CRM 2013

when there is many to many or n to n (n:n) relationship is created between two entities, CRM creates new table as connection or a bridge between these entities to store id’s of both entities. Suppose there is a student and he has been studied in different institutes and there could be n:n relationship between them lets say

there relationship name is (crm database table name) crm_student_institute

target entity could be student

linked entity could be institute so

//string strEntityRelationshipName = crm_student_institute
//CrmServiceProvider serviceProvider is new crm 2013 service provider which contains IOrganisationService object inside of it serviceProvider.Service
//Entity targetEntity = Student Entity
//Entity linkedEntity = institute entity
public static bool AssociateManyToManyEntityRecords(CrmServiceProvider serviceProvider, Entity targetEntity, Entity linkedEntity, string strEntityRelationshipName)
    AssociateRequest request = new AssociateRequest();
    EntityReference targetEntityReference = new EntityReference(targetEntity.LogicalName, targetEntity.Id);
    EntityReference linkedEntityReference = new EntityReference(linkedEntity.LogicalName, linkedEntity.Id);
    request.Target = targetEntityReference;
    request.RelatedEntities = new EntityReferenceCollection { linkedEntityReference };
    request.Relationship = new Relationship(strEntityRelationshipName);


    return true;
