使用 NET.TCP 绑定的 Ninject WCF 扩展 ArgumentNullException

发布于 2024-10-26 11:30:14 字数 1922 浏览 14 评论 0原文

我有一个 WCF 4 服务，有 2 个端点配置为使用 wsHttpBinding 和 netTcpBinding。我使用 WAS 在 IIS 7.5 中托管该服务，并使用 Ninject WCF 扩展来 DI 到我的服务中。当我使用 wsHttpBinding 端点调用我的服务时，我的服务工作正常，但当我使用 netTcpBinding 时失败。当我查看应用程序事件日志时，出现下面概述的错误。

我尝试在 VS2010 中调试该问题，但进展缓慢。如果可能的话，我不想从我的 WCF 服务中删除 Ninject。我知道我可以只使用 wsHttpBinding，但这是一项内部服务，我希望获得 netTcpBindings 提供的性能提升。

有没有人可以帮助解决这个问题？对此的任何帮助将不胜感激。

I have a WCF 4 service with 2 endpoints configured to use wsHttpBinding and netTcpBinding. I am hosting the service within IIS 7.5 using WAS and am using the Ninject WCF extension to DI into my service. My service works fine when I use the wsHttpBinding endpoint to call my service but fails when I use the netTcpBinding. When I look in my Application Event Log I get the following error outlined below.

I have tried debugging the problem in VS2010 but am getting nowhere fast with this. I don’t want to have to remove Ninject from my WCF service if at all possible. I understand that I could just use wsHttpBinding but I this is an internal service and I want to get the performance gains that netTcpBindings provide.

Is there anybody out there that may be able to help with this problem? Any help on this one would be much appreciated.
