Question

我有其他公司编写的WCF 3.5服务，但我有源代码。我有两个客户端，第一个是Silverlight（由同一家公司编写）和第二个ASP页面。

我在WCF网站上有以下错误：

using(((WindowsIdentity)HttpContext.Current.User.Identity).Impersonate())
{
    SomeClass.SomeMethod();
}

身份几乎相同。

silverlight电话的身份：

Name=Contoso\Administrator
Authenticated=True
Type=Negotiate
ImpersonationLevel=**Impersonation**
IsAnonymous=False
IsGuest=False
IsSystem=False

ASP Web呼叫的身份：

Name=Contoso\Administrator
Authenticated=True
Type=Negotiate
ImpersonationLevel=**Identification**
IsAnonymous=False
IsGuest=False
IsSystem=False

所以区别在于ImpresonationLevel值。你知道我该怎么办呢？

例外：

System.IO.FileLoadException: Could not load file or assembly 'System.Transactions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

我已经解决了我的问题。

要将ImpersonationLevel从标识切换为模拟，您必须更新客户端wcf行为配置。它看起来应该是这样的（最重要的是 allowedImpersonationLevel 属性）：

<system.serviceModel>   
    <client>
      <endpoint ... 
                behaviorConfiguration="ImpersonationBehavior" />
    </client>
    <behaviors>
       <endpointBehaviors>
          <behavior name="ImpersonationBehavior">
             <clientCredentials>
                  <windows allowedImpersonationLevel="Impersonation" />
             </clientCredentials>
          </behavior>
       </endpointBehaviors>
    </behaviors>
</system.serviceModel>

默认情况下，如果未指定任何内容，WCF将使用标识。
