我正在使用Visual Studio 2013，.NET4.5。
最初我是WCF服务消费者，但由于缺乏处理子系统的团队资源，我接管了WCF服务双方的开发。所以我得到了我需要的WCF服务代码在本地运行。通过删除旧的服务引用然后使用Visual Studio UI添加New Service Reference来插入它。它为我生成了客户端和配置。
它构建并运行正常但是当我调用该服务时出现错误：
C＃代码:(这里几乎无关紧要，但无论如何有人会要求它）
public class LeafManager
{
public LeafManager(ICorePricingService pricing, IWebQuoteService quote, IWebPaymentService payment)
{
this.Pricing = pricing;
this.Quote = quote;
this.Payment = payment;
}
public IWebPaymentService Payment { get; set; }
public IWebQuoteService Quote { get; set; }
public ICorePricingService Pricing { get; private set; }
public List<Core.WillProductValuation> GetWillProducts(bool? isMirror, List<Core.QuestionAnswer> questions,
List<string> discountCodes)
{
var result = this.Pricing.GetWillsPrices(new WillPricingParameters{Questions = questions.ToLeafPayment(), DiscountCodes = discountCodes.ToArray(), IsCouple = isMirror});
return result.ToLocal();
}
...
}

如果我们查看最里面的异常，它会声明The target principal name is incorrect，这意味着（WCF）生成了错误的UPN。我必须在这里遗漏一些明显的东西。
答案 0 :(得分：2)
自己想出来。
我需要做的就是删除
<identity>
<userPrincipalName value="matas.vaitkevicius@group......co.uk" />
</identity>
