WCF 访问被拒绝答案

【问题标题】：WCF Access DeniedWCF 访问被拒绝
【发布时间】：2012-07-10 09:19:13
【问题描述】：

我有一台本地化 WCF 服务的 PC，我可以在 C# 程序中添加对该服务的引用。但是，当我运行该程序时，我收到拒绝访问错误。除了拒绝访问之外，我没有得到任何其他信息。

有没有人对如何做有任何建议。我有另一台机器，它的设置看起来相同，但能够连接到同一台机器上的本地化版本。我查看了其他已发布的问题，但似乎没有任何问题。

【问题讨论】：

您至少应该发布您的客户端和服务器配置（来自 .config 文件或代码，具体取决于您使用的内容）。
检查您的代码的代码访问策略。似乎您的代码部分受信任。
根据要求，我已经更新了我的原始评论以包含配置文件。你有关于我需要做什么 Shailesh 的链接吗？用户详细信息在服务器上是正确的，只是在这里匿名。
谁说“拒绝访问”？启动应用时是 .NET 运行时，是 IIS 拒绝访问服务，在哪一行代码发生？
异常中的消息，只是说“拒绝访问”。当我调用 MakeRequest 时发生错误。

【解决方案1】：

发现问题出在哪里，很可笑。虽然我认为这是 IIS 或 .NET 的原因，但我和问题一样接近问题。问题是 Windows 防火墙被设置为阻止包括网络流量在内的所有内容。问题发布在这里是因为我认为它是 .NET 代码。

感谢 Grzegorz、CodeCaster 和 Shailesh 花时间阅读并提供建议。
