wcf - 如何使用 WCF 和自定义 ASP.NET 成员资格提供程序调试 'Default Membership Provider could not be found' 错误？

Question

这对我来说是在 IIS7.5 64 位上运行的 .Net 3.5 SP1 的问题(我尝试强制使用 32 位，但得到了相同的结果)。

我有一个 WCF 服务，我想与它一起使用身份验证服务。当我没有任何行为时，WCF 服务会在没有任何错误的情况下绘制(回复)。其他服务也适用于其他行为

一旦我将 userNameAuthentication 添加到指定自定义 MembershipProvider 以对服务进行身份验证的行为中...

  <serviceCredentials>
    <!-- Configure user name authentication to use the Membership Provider -->
    <userNameAuthentication userNamePasswordValidationMode ="MembershipProvider"
                            membershipProviderName ="MembershipService"/>
  </serviceCredentials>

服务崩溃并返回以下错误:

 Parser Error Message: Default Membership Provider could not be found.
 Source Error: 
 Line 49:     </authentication>
 Line 50:     
 Line 51:     <membership defaultProvider="MembershipService" userIsOnlineTimeWindow="15">
 Line 52:       <providers>
 Line 53:         <clear/>

事件日志有这个错误:

我很确定这不是提供程序或提供程序配置的问题，因为我有这个自定义提供程序与 ASP MVC 站点一起工作。

有什么想法吗？

我从头开始了一个新的自定义提供程序实现，以确保所有覆盖都正确返回。我原以为可以工作的(那是几个月前的)，但事实证明它不再有效。

事实证明，如果您的配置中的 Provider Name 和 Type 正确，则只会留下您的 Custom Provider 实现。

因此，如果您遇到此问题并且确定您的配置正确，请使用简单的 ASP.net 或 ASP.net MVC 网站验证您的实现。
