VS 2010 Beta 2 - 無法更新服務參考

Question

我正在將項目從VS2008升級到VS2010B2 由於某些原因，項目升級後，引用生成的代碼缺失，我無法重新創建通過重新配置服務引用，因爲我發現了以下錯誤代碼：

The configuration for the service reference could not be updated due to the following issue: An error occurred creating the configuration section handler for system.serviceModel/behaviors: Extension element 'webHttp' cannot be added to this element. Verify that the extension is registered in the extension collection at system.serviceModel/extensions/behaviorExtensions.

這臺機器有webHttp配置：

<system.serviceModel> 
    <extensions> 
    <behaviorExtensions> 
    ... 
    <add name="webHttp" type="System.ServiceModel.Configuration.WebHttpElement, System.ServiceModel.Web, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> 
    ... 
        </behaviorExtensions> 
    ...
