c# - ServiceHost的自定义Factory无法从GAC加载

Question

我在 IIS 中托管了一个 WCF 服务，该服务运行良好。实际上它按顺序使用以下 Global.asax 和 OrderService.svc 文件。

<%@ Application Codebehind="Global.asax.cs" Inherits="MyCompany.MyOrderServices.Global" Language="C#" %>

<%@ ServiceHost Language="C#" Debug="true" Service="MyCompany.ServiceLibrary.OrderServiceImpl"   Factory="MyCompany.ServiceLibrary.GenericServiceHostFactoryImpl, MyCompany.ServiceLibrary"%>

我正在尝试制作一个\bin\'less WCF 服务并将其托管在 IIS 中。我将所有必要的程序集放入 GAC。当我向服务发出请求时，出现以下错误:

Parser Error

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: Could not load the assembly 'MyCompany.MyOrderServices'. Make sure that it is compiled before accessing the page.

Source File: /global.asax Line: 1

好吧，我通过如下更改 Global.asax 文件修复了这个错误:

<%@ Application Codebehind="Global.asax.cs" Inherits="MyCompany.MyOrderServices.Global, MyCompany.MyOrderServices, Version=1.0.0.0, Culture=neutral, PublicKeyToken=XXXXXXXXXXX" Language="C#" %>

所以我明白了:我必须将简单的类型名称更改为类型的程序集限定名称。实际上，在我修复了 Global.asax 错误之后，我得到了以下错误。

Could not load file or assembly 'MyCompany.ServiceLibrary' or one of its dependencies. The system cannot find the file specified.

然后我启用了 Fusion 日志记录并获得了以下信息:

=== Pre-bind state information ===

LOG: DisplayName = MyCompany.ServiceLibrary

(Partial)

WRN: Partial binding information was supplied for an assembly:

WRN: Assembly Name: MyCompany.ServiceLibrary | Domain ID: 4

WRN: A partial bind occurs when only part of the assembly display name is provided.

WRN: This might result in the binder loading an incorrect assembly.

WRN: It is recommended to provide a fully specified textual identity for the assembly,

WRN: that consists of the simple name, version, culture, and public key token.

WRN: See whitepaper http://go.microsoft.com/fwlink/?LinkId=109270 for more information and common solutions to this issue.

显然省略了 GAC 文件夹。然后我更改了 .svc 文件，如下所示:

<%@ ServiceHost Language="C#" Debug="true" Service="MyCompany.ServiceLibrary.OrderServiceImpl, MyCompany.ServiceLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=XXXXXXXXXXX"   Factory="MyCompany.ServiceLibrary.GenericServiceHostFactoryImpl, MyCompany.ServiceLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=XXXXXXXXXXX"%>

...但是我遇到了同样的错误。 ServiceHost 指令有什么问题。为什么不能从 GAC 文件夹加载程序集？

(注意 1:顺便说一句；我检查了以下链接，建议将简单类型名称更改为程序集限定类型名称，但它对我不起作用。

Answer 1

哈!

我好像忘了编辑 Web.config:它还包含程序集名称。

<system.webServer>
  <modules runAllManagedModulesForAllRequests="true">
    <add name="CORSEnablingModule" type="MyCompany.ServiceLibrary.Cors.CORSEnablingModule, MyCompany.ServiceLibrary" />
  </modules>
</system.webServer>

现在，我已将其更改为完全限定名称，一切正常。

还是谢谢你
