是否可以配置自定义DataService <t>以允许模拟？</t>

Question

在“标准”WCF服务上，我只需用以下方法标记操作方法：

[OperationBehavior(Impersonation = ImpersonationOption.Allowed)]

但是使用我的数据服务，只要打开DataServiceHost，我就会收到InvalidOperationException：

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

如何标记'ProcessRequestForMessage'以允许模拟？

Answer 1

配置以下行为：

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