我正在学习WCF，特别是我正在学习如何先写下合同，ala wscf.blue
我可以通过最后的方式创建一个WCF客户端/服务（Microsoft） 我可以通过合同的第一种方式创建WCF客户端/服务（WSCF）
但是，如果我创建一个契约第一个服务，然后尝试添加Microsoft方式（服务引用）而不是WSCF.blue方式（共享契约和生成客户端）它不起作用。
它会抛出ActionNotSupportedException消息The message with Action 'urn:test-com:simple:testMethodIn' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).
我不知道这意味着什么。
这是我的测试合同：

如果我向http://localhost:50862/Simple.svc添加服务引用，则每个似乎都生成OK。
我使用服务配置编辑器通过导入web.config：
在客户端app.config中创建它<system.serviceModel>
<client>
<endpoint address="http://localhost:50862/Simple.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_SimpleInterface" contract="SI.SimpleInterface" name="NewPort"/>
</client>

<transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
<message clientCredentialType="UserName" algorithmSuite="Default"/>
</security>
</binding>
</basicHttpBinding>
</bindings>
</system.serviceModel>
如果我运行我的测试代码：
static void Main(string[] args)
{
SimpleInterfaceClient client = new SimpleInterfaceClient();
var ret = client.TestMethod(new PayloadType() { AnInt = 7, AString = "bob" });
Console.WriteLine(ret.ToString());
Console.ReadLine();
}
在TestMethod代理中包含以下行：
return base.Channel.TestMethod(request);
引发以下异常
System.ServiceModel.ActionNotSupportedException occurred

有人可以帮忙吗？

首次修改
好的，我现在发现我的doc-lit-wrapped wsdl和代码生成器出了问题。 wscf.blue不喜欢它的消息，可以将nullable类型标记为nillable。它不属于包装模式，方法实现也没有解开。
但是，如果我不将它们标记为nillable，则客户端代码将脱离包装模式，因为它们是可空类型，未标记为可为空。
可空类型标记为无法使用：
服务器端：
[System.ServiceModel.OperationContractAttribute(Action="urn:test-com:simple/ISimple/TestMethod", ReplyAction="urn:test-com:simple/ISimple/TestMethodResponse")]
[System.ServiceModel.XmlSerializerFormatAttribute(SupportFaults=true)]
[return: System.ServiceModel.MessageParameterAttribute(Name="Output")]
PayloadType TestMethod(PayloadType APayload);
客户端：
// CODEGEN: Generating message contract since element name APayload from namespace urn:test-com:simple is not marked nillable
[System.ServiceModel.OperationContractAttribute(Action="urn:test-com:simple:testMethodIn", ReplyAction="*")]
DesktopClientTest_ServiceReference.SI.TestMethodResponse TestMethod(DesktopClientTest_ServiceReference.SI.TestMethodRequest request);
可空类型标记为可为空：
服务器端：
// CODEGEN: Parameter 'Output' requires additional schema information that cannot be captured using the parameter mode. The specific attribute is 'System.Xml.Serialization.XmlElementAttribute'.
[System.ServiceModel.OperationContractAttribute(Action="urn:test-com:simple/ISimple/TestMethod", ReplyAction="urn:test-com:simple/ISimple/TestMethodResponse")]
[System.ServiceModel.XmlSerializerFormatAttribute(SupportFaults=true)]
[return: System.ServiceModel.MessageParameterAttribute(Name="Output")]
TestMethodResponse TestMethod(TestMethodRequest request);
客户方：
[System.ServiceModel.OperationContractAttribute(Action="urn:test-com:simple:testMethodIn", ReplyAction="*")]
[return: System.ServiceModel.MessageParameterAttribute(Name="Output")]
DesktopClientTest_ServiceReference.SI.PayloadType TestMethod(DesktopClientTest_ServiceReference.SI.PayloadType APayload);
然而，我不知道这是否是原因，更不用说如何解决它。 也就是说，我做知道可以为文件包含的wsdl标记可为空的类型。
答案 0 :(得分：1)
I think the problem is contract. In client generated, you can see contract="SI.SimpleInterface", but in service definition contract="ISimple".
