Question

I created a simple wcf service that retrieves data from crm 4.0 using the advanced developer tools. I queried the data successfully using linq. The classes were generated using crmsvcutil. However, when I converted this to a wcf service as below it keeps crashing.

namespace CRMDataRetrieval
 {    
 [ServiceContract]
public interface ICRMData
{
    [OperationContract]
    string getValue();

}

public class CRMDataService : ICRMData
{
    public string getValue()
    {
        DataContext context = new DataContext("entities");  //entities is name of    classes that were generated by crmsvcutil

        string name = null;
        var query = from n in context.contacts
                    where n.acctNum == "01218515"
                    select n.nickname;
        foreach (var result in query)
            name = result;
        return name;
    }

In the WCF Service Host, the service is stopped but it also shows Entities.CmsDataService as being stopped as well. When i click on this, the additional Information says that The service(Entities.CmsDataService) cannot be started. This service has no endpoint defined. Please add at least one endpoint for the service in config file and try again.

As things stand my app.config looks like below. So how and where would I add the endpoints in the config file for the autogenerated classes so that they work nicely with WCF? or would I need to make any other changes? Please be detailed in your explanation. As usual, thanking you in advance.

Look at crmsvcutil parameters. There are /dataContextPrefix and /dataContextClassName. Use these parameters to set proper name for generated data context. Use the generated context as it described here

CrmConnection crmc = CrmConnection.Parse("Authentication Type=Passport; Server=https://" + org + ".crm.dynamics.com/" + org + "; User ID=myuser; Password=mypassword; Device ID=mydeviceid; Device Password=mydevicepassword");
var yourDataContext = new GeneratedDataContext(crmc);

Unfortunately I don’t have CRM 4.0 installed. But I can provide code for CRM 2011:

namespace CRMDataRetrieval
{
    public class CRMDataService : ICRMData
    {
        public string getValue()
        {
            var connection = CrmConnection.Parse("Url=https://orgname.crm.dynamics.com; Username=OpenId; Password=; DeviceID=####; DevicePassword=####");
            var service = new OrganizationService(connection);
            MyServiceContext context = new MyServiceContext(service);

            string name = null;
            var query = from n in context.ContactSet
                        where n.ContactId == new Guid("00000000-0000-0000-0000-000000000000")
                        select n.FullName;
            foreach (var result in query)
                name = result;

            return name;
        }
    }
}

I used endpoint configuration you provided.

To generate classes I used

crmsvcutil.exe /url:https://orgname.crm.dynamics.com/XRMServices/2011/Organization.svc /out:GeneratedCode.cs /n:MyCrmNamespace /u:"OpenId" /p:"####" /serviceContextName:MyServiceContext /di:#### /dp:####
