我正在尝试从Juval Lowy 的网站（Programming WCF Services 的作者和 IDesign 的创始人）编译/运行示例WCF 应用程序。该应用程序是需要使用VS 2010/.Net 4的发布/订阅“交通灯”应用程序的示例。这是我第一次尝试使用 VS 2008/Net 3.5 以外的任何东西。
最初我收到以下绑定错误：
“找不到配置绑定扩展‘system.serviceModel/bindings/netOnewayRelayBinding’。”
此错误似乎可以通过修改 .Net 4 machine.config 文件来解决，以合并 .Net 2 machine.config 文件中的以下引用。

不幸的是，运行应用程序会导致以下安全错误：
为 system.serviceModel/client 创建配置节处理程序时出错：该程序集不允许部分受信任的调用者。
（\TrafficLights\TrafficController\bin\Debug\TrafficController.vshost.exe.Config 第 4 行）

我知道 Juval 的代码在这里没有错，这一定是我在 VS 2010 配置中做错了什么。我一直无法在网上找到解决方案。有人可以指导我如何最好地处理这个问题吗？
