在Mac Os X上使用Mono控制台应用程序托管WCF服务

wcfmono
3
当我试图在Mono控制台应用程序中托管一个在Windows中完美运行的WCF服务时，我会收到以下错误信息（*）：
“字典中已经存在具有相同键的元素。”
我完全不明白为什么会发生这种情况，或者我需要去哪里寻找解决方案。有没有谁遇到过这个问题，或者可以指点我正确的方向？
我正在使用运行Os X 10.6.8的Mac上的Mono 2.10.8。

我已经能够运行代码的一个子集，但由于代码库的复杂性，我不知道这个非常普遍的错误的确切原因。似乎有多个问题导致了这个错误，包括（i）不完全支持WCF服务发现，（ii）服务契约继承的怪异行为以及（iii）不受支持的Azure库。我正在调查这个问题，并将报告我发现的任何解决方案。 - dsfgsho
我已经提交了 https://bugzilla.xamarin.com/show_bug.cgi?id=6187 这个问题，看起来与你的问题相似。你在继承的操作上是否有行为（比如 WebGet）？ - sisve
是的，我做到了。最终通过将所有操作移动到一个服务合同中来修复它。 - dsfgsho
