Question

我创建了一个简单的wcf服务，它使用高级开发人员工具从crm 4.0中检索数据。我使用linq成功查询了数据。这些类是使用crmsvcutil生成的。但是，当我将其转换为wcf服务时，它会一直崩溃。

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;
    }

在WCF服务主机中，服务已停止，但它也显示Entities.CmsDataService也已停止。当我点击它时，附加信息表明无法启动服务（Entities.CmsDataService）。此服务没有定义端点。请在配置文件中为服务添加至少一个端点，然后重试。

我的app.config看起来如下所示。 那么我如何以及在何处在自动生成的类的配置文件中添加端点，以便它们与WCF一起很好地工作？或者我需要进行任何其他更改？ 请在解释中详细说明。像往常一样，提前感谢你。

Answer 1

你能提出一个hello world端点并使用它吗？完成后，您可以使用已编写的工作代码。（除非crmsvcutil生成一些专门用于托管wcf端点的类，我不知道？）

我同意paramosh - 'Entities.CmsDataService'不是我希望给你的例子服务的名称。我原本期望'CRMDataRetrieval.CRMDataService'

Answer 2

看看crmsvcutil parameters。有/ dataContextPrefix和/ dataContextClassName。使用这些参数为生成的数据上下文设置正确的名称。使用生成的上下文，如here

所述

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);

不幸的是我没有安装CRM 4.0。但我可以为CRM 2011提供代码：

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;
        }
    }
}

我使用了您提供的端点配置。
