WCF和带模板的数据契约

我刚刚开始与WCF合作，面临一个我无法处理的问题。我有一些代码如下

当我试图在客户端调用GetPoints时，我得到一个异常

这似乎是某种序列化问题，我试图增加网络tcp绑定缓冲区（MaxBufferSize、MaxReceivedMessageSize），但没有帮助。有没有办法解决这个问题？

如果这个错误发生在.net和mono之间，那么它很可能是由这个错误引起的

Mono的nettcpbinding实现错误地编码了可变长度字段。这意味着，对于.net客户机，在处理mono的响应时，某些接口方法调用将起作用，而其他接口方法调用将抛出“以下元素未关闭：信封”错误

[ServiceContract(SessionMode=SessionMode.Required, CallbackContract = typeof(IServiceCallback))]
[ServiceKnownType(typeof(Point))]
public interface IService
{
    [OperationContract]
    Point[] GetPoints();
}

public sealed class Service : IService
{
    public Point[] GetPoints()
    {
        var p = new [] { new Point { Name = "point_1", Value = 1.1F } };
        return p;
    }
}
