对于我来说,这是IIS4.5 64位上运行的.Net 3.5 SP1的问题(我尝试强制32位但得到了相同的结果).

我有一个WCF服务,我想使用身份验证服务.当我没有行为时,WCF服务绘制(回复)而没有任何错误.其他服务也适用于其他行为

只要我将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>

该服务爆炸并返回以下错误：

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/>

事件日志有此错误：

我很确定这不是提供者或提供者配置的问题,因为我有这个自定义提供者使用ASP MVC站点.

有什么想法吗？

解决方法

我从头开始创建一个新的自定义提供程序实现,确保所有覆盖都正确返回.我原来的那个,我认为是在工作(那是几个月前),事实证明它已经不再适用了.

事实证明,如果您的提供商名称正确且配置中的类型正确,则只会离开您的自定义提供程序实现.

因此,如果您遇到此问题且确定配置正确,请使用简单的ASP.net或ASP.net MVC网站验证您的实施.
