无法在ServiceModel客户端配置部分中找到引用合同'''的默认端点元素

Question

让我告诉你我的项目结构，我的服务是由一个类库项目调用的，而我的客户端应用程序又调用了它，它是outlook的一个插件。我的类库和客户端项目都有相同的绑定配置。 注意 - 当我在本地运行代码时，我没有收到此错误，但是当我将其部署到其他计算机（或服务器）时，它会抛出此错误。

自从我面对这个问题差不多一周后，请帮助我。提前谢谢。

错误：

无法在ServiceModel客户端配置部分中找到引用合同“CreateContactService.ICreateContactService”的默认端点元素。这可能是因为没有为您的应用程序找到配置文件，或者因为在客户端元素中找不到与此合同匹配的端点元素。

C＃代码呼叫服务方法

    private static CreateContactServiceClient _GetClientService = default(CreateContactServiceClient);
_GetClientService = new CreateContactServiceClient();

            List<Contact> contactsFromDb = new List<Contact>();
 contactsFromDb = getClientServices.GetContacts();
