在.NET 4.0中的web.config编译错误 - 找不到的Linq [英] Compilation error in .NET 4.0 web.config - Linq not found

问题描述

我可以编译和Visual Studio 2010中的测试我的.NET 4.0中的Web应用程序就好了但是如果我点我本地IIS文件夹包含应用程序，我得到以下错误：

I can compile and test my .NET 4.0 web application just fine within Visual Studio 2010. If, however I point my local IIS to the folder containing the application, I get the following error:

Compiler Error Message: CS0234: The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?)
Source Error:
Line 388:                <add namespace="System.ComponentModel.DataAnnotations" />
Line 389:                <add namespace="System.Configuration" />
Line 390:                <add namespace="System.Linq" />
Line 391:                <add namespace="System.Text" />
Line 392:                <add namespace="System.Text.RegularExpressions" />

Source File: c:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config    Line: 390 

它是如何从框架的Web.config将无法编译适合我？

How is it that the web.config from the framework won't compile for me?

我发现在网络上类似的问题，大部分只是说添加此引用...，但它不可能是正确的事情，以编辑默认的web.config - ？可它

I have found similar problems on the web and most just say 'add this reference...', but it can't be the right thing to edit the default web.config -- can it?

推荐答案

这为我工作。有这种组件在web.config文件

This worked for me. Have this assemblies in the web.config file

<compilation debug="true">
      <assemblies>
        <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
        <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
        <add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
        <add assembly="System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
        <add assembly="System.Web.Extensions.Design, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add assembly="System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
      </assemblies>
    </compilation>
  </system.web>
