Sample Code for using IOrganizationService in CRM 2011

Just a sample code for quick reference !

Uri organizationUri = new Uri("http://crmservername/orgname/XRMServices/2011/Organization.svc");
Uri homeRealmUri = null;
ClientCredentials credentials = new ClientCredentials();
// set default credentials for OrganizationService
credentials.Windows.ClientCredential = (NetworkCredential)CredentialCache.DefaultCredentials;
// or
credentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
OrganizationServiceProxy orgProxy = new OrganizationServiceProxy(organizationUri, homeRealmUri, credentials, null);
IOrganizationService _service = (IOrganizationService)orgProxy;
    Entity myAccount = new Entity("account");
    myAccount["name"] = "Test Account";
catch (Exception ex)

In case of early-bound, don’t forget to add the following line of code

 OrganizationServiceProxy _serviceProxy = new OrganizationServiceProxy(organizationUri, homeRealmUri, credentials, null);
 // This statement is required to enable early-bound type support.
  _serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());

  1. Please help me!
    I run example “quickstart” in SDK Microsoft Dynamic CRM 2011 and thrown exception:

    Could not load file or assembly ‘Microsoft.IdentityModel, Version=, Culture=neutral, PublicKeyToken=31bf38564e35’ or one of its dependencies. The system cannot find the file specified.

    Can you help me fix it?
    Note: My operation operating system is “Win xp sp3 build 2600” -> I can’t setup Microsoft Identity Model.


    1. Hi How to assing my custome guid while creating entity in CRM 2011 using IOrganizationService in CRM 2011


  2. Can you help me fix it?
    Metadata contains a reference that cannot be resolved: ‘http://server02/XRMServices/2011/Discovery.svc?wsdl’.


  3. OrganizationServiceProxy _serviceProxy = new OrganizationServiceProxy(organizationUri, homeRealmUri, credentials, null);

    If i am not mistaken in this statement the last parameter is device credentials ( i.e. deviceID and DevicePassword) , could you specify for what reson these are passed and in which senario we would pass them.

    I need to build connection using Windows live ID. Any specific points to note of it.


    1. Hi,

      Were you able to connect your app using Windows Live Id ?
      In fact i get an exception which says ” Value cannot be null. Parameter name: DeviceCredentials ”
      Any idea what would be going wrong ?


      1. Hi was able to successfully connect.
        Device Credentials are always needed while connecting to Online MS CRM.

        For this use the deviceidmanager.cs from the helper code. have the needed dlls added.
        Make sure the timestamp ( clock skew) is in synch with that of the online CRM.

        It should work.


      2. Hi Sanu,

        Take a look at soaplogger sample in CRM 2011 SDK


        It makes use of crmservicehelpers.cs which would be of interest to you.


  4. Hi,

    I tried running the code as is and I get an error saying:

    “base {System.ServiceModel.CommunicationException} = {“The token provider cannot get tokens for target ‘http://crm2011/CRM/XRMServices/2011/Organization.svc’.”}”

    Could some one please help as I cannot figure this out.

    Thanks in advance


  5. Hi!
    When I run a sample in CRM 2011 SDK to add a note with a document attachment to the contact’s record. It throws exception:
    “The request channel timed out while waiting for a reply after 00:01:59.9069947. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted tho this operation may have been a portion of a longer timeout.”
    Note: I use CRM 2011 online. File upload has size 6M, type zip. I set file size limit for attachments to 8M.
    I hope you can help me. Thanks!


    1. Hi TrongNguyen,

      Create the registry entries as mentioned in this KB article, also increase the timeout in CRM’s all web.config files, you will need to change these two keys in web.config files executionTimeout=”3600″ maxRequestLength=”20000″, restart your IIS and Async Services instance and I think you will fine.


  6. Hello,

    How to avoid of using

    new System.Net.NetworkCredential(“admin”,“pwd “,“domain”);

    but use WindowsIdentity or pass NTLM authentication details?


    1. Try this Sultan

      ClientCredentials credentials = new ClientCredentials();

      // set default credentials for OrganizationService

      credentials.Windows.ClientCredential = (NetworkCredential)CredentialCache.DefaultCredentials;

      // or

      credentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;

      Let me know it worked or not.


      1. What are the reasons for the failure of ‘…/XRMServices/2011/Organization.svc’?
        I try to test but the CRM says but 20 minutes ago I was ok

        An error has occurred.

        Try this action again. If the problem continues, check the Microsoft Dynamics CRM Community for solutions or contact your organization’s Microsoft Dynamics CRM Administrator. Finally, you can contact Microsoft Support.


        1. Try by adding the following line

          IOrganizationService service = (IOrganizationService)serviceProxy;

  12. Hi Nishant,
    I am working with website connecting to CRM 2011. I am stuck up with idea of passing credentials of the logged in user to crm 2011. If I surpass following lines of code I get SSPI error while updating

    ClientCredentials credentials = new ClientCredentials();
    // set default credentials for OrganizationService
    credentials.Windows.ClientCredential = (NetworkCredential)CredentialCache.DefaultCredentials;
    // or
    credentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;

    Please suggest on this.

    A design like yours with a few simple tweeks would really make my blog stand out.
    Please let me know where you got your theme. Kudos
