CrmConnection Did not work anymore in MS CRM Dynamics Update 2015 RRS feed

  • Question

  • We develop a Web Api that connects to out CRM Dynamics. We use our webapi to get our leads in CRM. Its was working, but now we cant connect anymore.

    We think its the Authentication. How are we able to connect to CRM Dynamics using the class CrmConnection.

    Do I have to register our webapi in Azure? And use the ClientId to authenticate?

  • Hi Bruno,

    You dont have to register your webapi in Azure..

     String X = "Url=" + OrganizationUrl + ";";
     X += " Domain="+Domain+"; Username=" + UserName + "; Password=" + Password + "";
    IOrganizationService _service = CrmConfigurationManager.CreateService(CrmConnection.Parse(X), "myservice") as IOrganizationService;

    Also you need add below tags into the Web.config file.

        <section name="microsoft.xrm.client" type="Microsoft.Xrm.Client.Configuration.CrmSection, Microsoft.Xrm.Client"/>
          <add name="Xrm" type="Xrm.XrmServiceContext, Xrm" serviceName="MyService"/>
          <add name="myservice" type="Microsoft.Xrm.Client.Services.OrganizationService, Microsoft.Xrm.Client" instanceMode="PerRequest"/>

  • Hello Aydin

    Thanks for your reply.

    My connection is pretty the same:

    CrmConnection connection = CrmConnection.Parse(ConfigurationManager.ConnectionStrings["UserAndPswrd"].ConnectionString);

    But its failling:

    An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail.

    I am not sure if is able to connect to MS CRM Dynamics like that. Because now the have their own Web Api (the webapi preview).

    I checking out your blog, there are good content there.

    Thanks :)

  • Hello, a simple example of my code. I removed some comments too.

    Thanks for your help.

    We implemented just one method:

    using System;
    using System.Web.Http;
    using System.Configuration;
    using Microsoft.Xrm.Client;
    using Microsoft.Xrm.Client.Services;
    using Microsoft.Xrm.Sdk;
    using System.Web.Http.Cors;
    using System.Net.Http.Formatting;
    using System.Web;
    using Microsoft.Xrm.Sdk.Query;
    using System.Collections;
    namespace CRMLead.Controllers
            origins: "http://localhost:54163",
            headers: "*",
            methods: "get")]
        public class CRMLeadController : ApiController
            private OrganizationService _orgService;
            public IEnumerable Get()
                CrmConnection connection = CrmConnection.Parse(ConfigurationManager.ConnectionStrings["CRMOnlineO365"].ConnectionString);
                using (_orgService = new OrganizationService(connection))
                    QueryExpression query = new QueryExpression
                        EntityName = "lead",
                        ColumnSet = new ColumnSet("fullname", "leadid")
                    return _orgService.RetrieveMultiple(query).Entities;


    An exception of type 'System.ServiceModel.Security.MessageSecurityException' occurred in Microsoft.Xrm.Sdk.dll but was not handled in user code

    An error occurred when processing the security tokens in the message.
