我收到了传说中的Error: Cannot obtain Metadata from...
消息,特别是http://localhost:1640/Service1.svc
我搜索了 stackoverflow 和 Google,到目前为止,这些都没有帮助。我创建了一个新产品来降低它的性能,但它仍然无法正常工作。所以我在这里寻求帮助。
我正在尝试设置一个使用 JSON 的 WCF 服务,这意味着我需要在 C# 中使用 webhttpbinding。当我使用 WCF 测试客户端时,出现上述元数据错误。我正在使用 Visual Studio Express 2010 和目标框架。我已经在这两天了,不明白为什么或什么问题。
我将不胜感激任何帮助。谢谢你。
这是我的 web.config 文件:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />

<system.serviceModel>

这是 IService1.cs 文件:

// Use a data contract as illustrated in the sample below to add composite types to service operations.
