我創建了一個非常簡單的WF4服務，其中只包含接收/發送序列。我已經部署到AppFabric，它通過瀏覽器查看時的響應如預期（即「您已創建服務」... wsdl鏈接..等）爲WF4工作流服務添加服務引用不會創建客戶端（ClientBase）
我在VS2012中添加了服務引用，它成功完成。但是，沒有引用ClientBase類（ServiceClient）。
但是，如果不是添加服務引用創建通過
svcutil.exe http://localhost/TrinityServices/Testbed/Service2.xamlx?wsdl
產生的Service2.cs顯然擁有ServiceClient宣佈服務2類，
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
public partial class ServiceClient : System.ServiceModel.ClientBase<IService>, IService
，我能聲明：
var svc = new ServiceClient();
.
.
string p = svc.GetData();
爲什麼客戶端類沒有通過服務引用生成過程？以下是完整的wsdl。
我碰到過一個類似的帖子（ClientBase classes are not available in Reference.cs file），但我看不到與我的問題有直接關係。我的名字空間不受默認值的影響。
感謝您的閱讀！
