WCF-具有Microsoft .NET客戶端的Mono服務器

Question

我有一個.NET客戶端和服務器，可以在Windows上使用NetTcpBinding和Microsoft .NET Framework來工作。

我想允許使用Mono 3.2.7在Linux上運行服務器。 但是，當Microsoft .NET客戶端嘗試在Mono服務器上調用方法時，它會收到以下錯誤消息：

無法聯系代理192.168.0.xx：反序列化“ MyMethod”操作的回復消息正文時出錯。 空的名稱空間要求使用null或空前綴。

空的名稱空間要求使用null或空前綴。

我已經四處搜尋，但是沒有任何有關如何解決此問題的線索。

*更新*

我只是用BasicHttpBinding嘗試了一下，然后再次在Microsoft .NET Framework上正常工作-但仍然不能與Mono一起工作。 我得到的錯誤與NetTcpBinding得到的錯誤類似：

無法為當前元素使用的前綴''重新定義名稱空間

服務器給出以下堆棧跟蹤：

顯然，這與序列化有關，但不止於此。

我啟動了Wireshark，以查看數據在網絡上的樣子，並且發送到Windows服務器和Mono服務器的HTTP POST看起來完全一樣。

Answer 1

要使此工作正常運行，有兩個部分（令人討厭的是，這兩個部分僅在Mono中才需要，而在Microsoft .NET中則不需要）：

1. 在將在線發送的類的DataContract屬性上，將IsReference設置為true： [DataContract(IsReference = true)]

2. 不要設置一個命名空間的DataContract在這些類屬性
