WCF 服务。我第一次尝试使用 WCF 参加 IoC。从控制台应用程序调用服务进行测试。有趣的是，我认为这些服务正在运行，所以我使用它们来提供数据来测试我正在研究的 POC……我几乎不知道我最终会修复这些服务！
（使用 Cassini 进行调试）
我正在使用的版本：
- FluentNHibernate 1.1.0.685
- NHibernate 2.1.2.4000
- 忍者 2.2.0.0
- Ninject.Extensions.Wcf 2.2.0.0
- .NET 框架 3.5
这是我用作参考的示例之一：Pieter De Rycke 的博客
我在 SO 上找到的几乎每一篇文章都与 MVC 相关……我认为我的问题略有不同，因为这是 WCF 而不是 MVC。
例外：
Error activating IAuditRepository
No matching bindings are available, and the type is not self-bindable.
Activation path:
2) Injection of dependency IAuditRepository into parameter auditRepository of constructor of type ShotService
1) Request for ShotService
Suggestions:
1) Ensure that you have defined a binding for IAuditRepository.
2) If the binding was defined in a module, ensure that the module has been loaded into the kernel.
3) Ensure you have not accidentally created more than one kernel.
4) If you are using constructor arguments, ensure that the parameter name matches the constructors parameter name.
5) If you are using automatic module loading, ensure the search path and filters are correct.
控制台应用程序失败代码：（ 在最后一行失败）
ShotServiceClient shotSvc = new ShotServiceClient();
LookupShotAdministeredRequest request = new LookupShotAdministeredRequest();
request.ClientId = "128";
request.ClinicId = "289";
request.RequestingUserId = "1";

我在 CreateKernel() 中放了一个断点，它没有被击中。我还在 NHibernateModule.cs 的 Load() 中设置了一个断点，该断点也没有被击中。 <-- 更正...卡西尼“没有响应”所以我想我并没有真正调试我的所有代码。我刚刚在 Cassini 上执行了一个结束任务，并在我的服务上重新运行了调试器……我在 CreateKernel() 中的断点被命中，我在 Load() 中的断点也被命中。我的主要问题仍然存在，但至少我知道这段代码正在执行。
