Question

我正在尝试开发一个在64位环境中运行的简单WCF服务。我在Windows 7下启动VS2010

新解决方案 - ＆gt; WCF项目 - ＆gt;运行 - ＆gt;它工作正常。

只要我更改项目的属性以使其以64位进行编译，运行它会引发以下异常：

Could not load file or assembly 'WcfService2' or one of its dependencies.

使用以下装配加载跟踪

=== Pre-bind state information ===
LOG: User = *****

WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: WcfService2 | Domain ID: 4
WRN: A partial bind occurs when only part of the assembly display name is provided.

我该如何克服这个问题？任何的想法？感谢

修改

将平台目标设置为AnyCPU后，WCF 进行编译，但我需要专门设置64位编译，因为我正在使用SharePoint对象和AnyCPU（或x86）编译结果同样的问题和错误描述here（以及在网上的其他地方）。

因此，我编译AnyCPU / x86并从SharePoint集成中收到错误，或者我将目标平台设置为64位，我从WCF收到错误。

Answer 1

您的WcfService2程序集是否标有Platform Target == x86？您应该尝试确保将其编译为任何CPU。您可以在Visual Studio项目设置的“构建”页面中找到此设置。

Answer 2

浏览到应用程序池的高级设置。将“启用32位应用程序”设置为true

Answer 3

经过长时间的研究，我找到了解决方案。问题是，当您使用64位运行应用程序时，IIS Express还需要作为64位进程运行（默认情况下，它是32位进程）。要使其成为64位，Visual Studio中提供了一个选项。工具->选项->项目和解决方案-> Web项目->使用IIS Express的64位版本。

Voila，它起作用。
