我有WCF数据服务，当直接通过浏览器查询时，它非常有效。然而，当我试图从VisualStudio2010中查询并绑定到网格时，它抛出一个DataServiceQueryException，告诉我“未找到资源”404错误。这真的很奇怪。有什么想法吗？

您是否自行主持该服务？测试服务时，您是否在VS dev服务器中运行它

我的想法是，当您尝试添加服务引用时，该服务可能没有实际运行。

这仍然存在问题。服务托管在客户机中。以下是全部错误：

@sv88erik，我不明白。“查找VS所有函数”是什么意思？服务（.svc文件）位于主客户端应用程序中，但服务代码位于类库中。我想了想你说的话，但是在VSI中无法与客户端一起启动类库我不知道我是否在正确的轨道上，但是在VS中可以同时启动2个以上的项目。一旦第一个应用程序运行，右键单击第二个项目并选择“调试>启动新实例”
