在本地系统中托管 [英] hosting in local system

问题描述

我在应用程序中使用wcf服务开发了一个Web应用程序.它工作正常.但是我的问题是，当我在iis(本地系统)中托管时，它显示错误，例如

``/WCFService''应用程序中的服务器错误.
配置错误
说明:在处理服务于此请求所需的配置文件期间发生错误.请查看下面的特定错误详细信息，并适当地修改您的配置文件.

解析器错误消息:无法加载文件或程序集"System.Web.Extensions，版本= 4.0.0.0，区域性=中性，PublicKeyToken = 31bf3856ad364e35"或其依赖项之一.系统找不到指定的文件.

源错误:

第22行:< compilation debug ="true">
第23行:<装配体>
第24行:< add assembly ="System.Web.Extensions，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = 31BF3856AD364E35"/>
第25行:< add assembly ="System.Data.Linq，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = B77A5C561934E089"/>
第26行:</assemblies>


源文件:c:\ inetpub \ wwwroot \ WCFService \ web.config行:24

程序集加载跟踪:以下信息有助于确定为什么无法加载程序集``System.Web.Extensions，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35''.

WRN:程序集绑定日志记录已关闭.
若要启用程序集绑定失败日志记录，请将注册表值[HKLM \ Software \ Microsoft \ Fusion！EnableLog](DWORD)设置为1.
注意:与程序集绑定失败日志记录相关的性能损失.
要关闭此功能，请删除注册表值[HKLM \ Software \ Microsoft \ Fusion！EnableLog].

我的web.config文件是::

< system.web>
<！-
将编译设置为debug ="true"以插入调试
符号插入已编译的页面.因为这个
影响性能，将此值仅设置为true
在开发过程中.
->
< compilation debug ="true">
<装配体>
< add assembly ="System.Web.Extensions，版本= 4.0.0.0，文化=中性，PublicKeyToken = 31BF3856AD364E35">
< add assembly ="System.Data.Linq，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = B77A5C561934E089">

Hi,

I developed one web application using wcf services in my application.It working fine.But my problem is,when i hosted in iis(my local system),it showing an error like,

Server Error in ''/WCFService'' Application.
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Could not load file or assembly ''System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'' or one of its dependencies. The system cannot find the file specified.

Source Error:

Line 24: <add assembly="System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

Line 26: </assemblies>


Source File: c:\inetpub\wwwroot\WCFService\web.config Line: 24

Assembly Load Trace: The following information can be helpful to determine why the assembly ''System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'' could not be loaded.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

My web.config file is::

<system.web>
<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.
-->
<compilation debug="true">
<assemblies>
<add assembly="System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
<add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089">



please give me any idea to solve this error

thanks,

推荐答案

Hai，

请转到C:\ WINDOWS \ assembly，然后检查System.Web.Extensions程序集名称，版本，公共密钥令牌是否存在.

如果其中任何一项发生了更改，则需要安装最新的框架.本地系统中未安装版本Framework 4.0.

希望这对您有帮助...

Hai,

Please go C:\WINDOWS\assembly and check the System.Web.Extensions Assembly Name ,Version,public Key token exists.

If any of these changed then you need to install latest framework.The version Framework 4.0 is not installed in your local system.

Hope this helps...

尝试以下两个步骤(如果需要，请用Framework64替换Framework):

转到:

C:\ Windows \ Microsoft.NET \ Framework \ v2.0.50727 \或已安装的版本
然后运行:

aspnet_regiis -i
转到:C:\ Windows \ Microsoft.NET \ Framework \ v3.0 \ Windows Communication Foundation

然后运行:

ServiceModelReg.exe -i

希望对您有所帮助.

Try these 2 steps (replace Framework with Framework64 if it''s needed):

Go to:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\ or the installed version
and then run:

aspnet_regiis -i
Go to: C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation

and then run:

ServiceModelReg.exe -i

I hope this helps.
