我一直试图解决这个问题将近2天，似乎没有取得多大进展。我有一个WCF服务设置（在VWD2008中使用VB开发）。在本地运行时，我能够看到带有WSDL页面链接的标准.svc帮助页面。
我把它移到服务器上并在尝试确保它之前重新测试 - 仍然正常工作。
然后我设置了一个自签名证书，这就是问题似乎开始的地方。我知道我的服务器和我的PC之间的证书身份验证工作（IIS7上设置了客户端证书），因为我可以在使用https时点击一个简单的.aspx页面。在这个阶段，当我尝试浏览.svc页面2时发生的事情 - 在IE中返回一个空白页面，在FF中我在黄色背景上收到以下消息
XML Parsing Error: no element found
Location: https://www.database-direct.com/vs.svc
Line Number 1, Column 1:
根据我的阅读，差异仅仅是因为FF处理空白页面的方式不同。
我很确定我的web.config文件是正确的，因为它几乎是另一个成功运行的服务的副本（虽然在运行IIS6的不同服务器上 - 配置文件会有任何差异吗？）

从我看到的这个看，它会建议某种IIS设置问题，我认为实际的服务似乎工作正常。我能想到的另一件事就是处理程序映射，但他们检查确定 - svc-ISAPI-2.0-64映射到*.svc
如果有人对我如何调试这个问题有任何进一步的建议（我已经与Fiddler一起检查过并且只是在页面加载时获得状态200）或者可能导致它的原因我会非常感激！
答案 0 :(得分：1)
我刚遇到这个问题。我认为是因为IIS中的MIME映射中缺少svc。
要解决此问题，您需要运行“\％windir％\ Microsoft.NET \ Framework \ v3.0 \ Windows Communication Foundation \ ServiceModelReg.exe -i”。它将创建所需的.svc映射。
如果你是64位，那么它的Framework64
