Question

我已经构建了一个由Windows服务托管在服务器上的WCF服务。一切正常，我已经测试了一些方法。现在我需要从我的客户端发送一个httprequest，如下所示：

 HttpWebRequest req = (HttpWebRequest)WebRequest.Create(String.Format(@"http://192.168.0.170:9001/myServ/Start/{0}/{1}", "blabla", "blabla"));
 req.Method = "GET";

问题是我在客户端持续收到异常，说明我的请求无效。我无法理解为什么。

这是我的wcf服务：

[OperationContract]
[WebInvoke(Method = "GET",
 UriTemplate = "Start/{param1}/{param2}")]
 string Mod(string param1, string param2);

这是我的配置

    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true"/>

我发现了问题。我使用visual studio 2015以调试模式托管我的WCF服务，以检查我的过程的各个步骤。我不知道为什么，但是虽然我对另一个方法没有任何问题，但是与get方法关联的处理程序有一个无法加载的程序集。我试图在Windows服务上托管服务，一切正常

错误400：httpwebrequest上的请求无效
