Question

在C＃中发布了一个发布的WCF服务。之前它正在工作，但是当我在前几天检查它时，它给了我错误。

这是剪切后的代码，然后是错误..任何人都可以告诉我什么是错的？感谢。

   [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Vending : IVNService, IUSAService
{

    //first method sent by VendNovation. Checks if the given student is allow to make vending purchases
    //will be rejected if: student not found in system or student is marked inactive
    public AuthenticateCustomerResult AuthenticateCustomer(AuthenticateCustomerRequest request)
.... .... .... ....

这是

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.NotSupportedException: A single WSDL document could not be generated for this service. Multiple service contract namespaces were found (http://vendnovation.com/, http://pos.usatech.com/). Ensure that all your service contracts have the same namespace.

at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)

被告知保持名称空间相同（vendnovation.com和pos.ustech.com），我的问题是为什么我们需要保持这两个名称相同？

这是我的代码IVNService.cs

[ServiceContract(Namespace = "http://vendnovation.com/")]
//[ServiceContract(Namespace = "http://vendnovation.com/"), XmlSerializerFormat]
public interface IVNService
{
.....  ......    .....

，这是来自另一个代码IUSAService.cs

//[ServiceContract(Namespace = "http://pos.usatech.com/"),     XmlSerializerFormat]
[ServiceContract(Namespace = "http://pos.usatech.com/")]
interface IUSAService
{

为什么我需要让它们保持相同的命名空间？

“该服务遇到了错误。” POST WCF REST服务
