使用 Windows 服务中托管的 WCF 服务的 Winform 收到错误 #405(方法不允许 e)

Question

WCF 服务承载在 Windows 服务中。我从 Web 浏览器获得了成功的响应，但我无法从 Winforms 应用程序中调用它。我总是收到错误#405。有什么想法吗？

我已经在我的 WCF 服务中启用了"CORS"，我从"Windows 功能打开和关闭"中打开了所有必需的组件。

这是我客户的app.config文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<diagnostics>
<messageLogging logEntireMessage="true" logMessagesAtServiceLevel="true"
logMessagesAtTransportLevel="true" />
<endToEndTracing propagateActivity="true" activityTracing="true"
messageFlowTracing="true" />

<endpoint 
address="http://localhost:8080/ "
behaviorConfiguration="AjaxBehavior"
binding="webHttpBinding"
contract="IScaleService" />
</client>
</system.serviceModel>
</configuration>

这是我的 WCF 服务配置文件：

<configuration>
<appSettings>
<add key="port" value="COM3"/>
</appSettings>

<endpointBehaviors>
<behavior name="AjaxBehavior">

最后，我发现了我的应用程序的问题。 自动生成的代理类未将 webget 属性添加到操作中。
