是否可以配置自定義DataService <T>以允許模擬？

Question

在「標準」 WCF服務我會簡單地標記的操作方法有：

[OperationBehavior(Impersonation = ImpersonationOption.Allowed)] 

但隨着我的數據服務，我只要DataServiceHost打開得到一個InvalidOperationException：

The service operation 'ProcessRequestForMessage' that belongs to the contract with the 'IRequestHandler' name and the 'http://tempuri.org/' namespace does not allow impersonation. 

如何標記'ProcessRequestForMessage'以允許模仿？

Answer 1

配置以下行爲：

<behavior> 
    <serviceCredentials useIdentityConfiguration="true" /> 
    <serviceAuthorization principalPermissionMode="Always" impersonateOnSerializingReply="true" /> 
</behavior>
